2.0.22

Fairy dust magic for better PageSpeed Scores (FCP, LCP, CLS)\n
- We’re going to be straight with you, this brings some magic pixie dust which will boost your Web Vitals. But you are boosting the score only and not actually changing anything real with the performance of the site. So if the score is important to you, then this will make you happy. But don’t fool yourself into thinking anything changed in actual speed, it just tests better and unfortunately a lot of people are judging yours and our works by a number generated by Google which currently doesn’t have a basis in reality. Hence us putting out this update because fair or not, people gonna judge.
- For more reading on the current problems in Web Vitals:
- Framehole: PageSpeed 6.0 loophole for easy perfect score
- Get a perfect Largest Contentful Paint (LCP) time with a single line of code
- Also fixed a minor bug(z-index) in the layout of our Classic Widget causing you to be unable to pick from your Media Library. Sorry about that and hat tip to Mirco for pointing it out!
- You’re among friends here. You are going to update for the PageSpeed Score improvement aren’t you? No judgement here, do what you need to do because business is a contact sport.
\n

2.0.21

2020 is nevermore, so it’s time for 2.0.21\n
- Look, everyone wants to forget 2020 and move forward to a better future in 2021. But our developers had one problem, Some how, some way, our plugin just happened to be at version 2.0.20. It was like a continuous nightmare where everytime we thought we were done with 2020, there it is again in our face. So what do developers do when faced with a problem……they solve it. We present the fresh new version 2.0.21. And just like the new year brings fresh optimism, so too did this version for our developers. Now they feel cheery, and ready to take on the world. Basically like they just finished a double espresso.
- Features….well this version brings inspiration, hope, and……some minor housekeeping fixes. Really let’s be honest, we are all ready for change, so here it is, version 2.0.21. Can’t be any worse than the last one right?
\n

2.0.20

CSS Conflict resolution update\n
- What happens when different plugins have a CSS conflict? If you answered Style Battle Royale, well then you are an interesting person who is probably fun at parties. But if you answered, “shrug things probably break?” You would be correct. Our new release prevents these style sheet conflicts where our player and your theme’s video player just couldn’t get along. Now they at least they are divided by a wall and can only stare angrily across the room.
- Namespaced the SmartVideo player CSS styles so that conficts between our video player and those included via your theme or other plugins should be eliminated. But there may be some sneaky conflicts we missed and if you see them, just reach out to support so we can take care of them. Thanks!
\n

2.0.19

No need to fear, dynamic tags are here\n
- Need to template up your massive video archive so that each post displays with the associated video in a SmartVideo tag. Easy breezy if you are an Elementor Pro user. Our SmartVideo widget can now dynamically load both the video source and/or poster image from any Elementor Pro dynamic tag. Quick, efficient, and beautiful
- Elementor SmartVideo widget supports dynamic tags for Elementor Pro users
\n

2.0.18

Now you see me, now you don’t\n
- Sometimes it’s fun to revert to our inner child and play games like hide & seek. Try it, we’ll wait. You really needed that, right? While games are good for humans, it’s not good for our Gutenberg block editor to play hide & seek with your block attributes. Naughty code was hiding the URL you set when you specified direct video URL’s in our SmartVideo block. Don’t worry we had a talk with the code, and it will never hide this data again. Also, rest assured everything is in there from previous blocks you have inserted, it was just…..hidden.
- Gutenberg block editor was not showing the URL’s you previously set for videos when you chose the “Another source” option. This has been fixed.
\n

2.0.17

Crouching tiger, hidden classic\n
- Fixed issue with SmartVideo Classic widget where you would click to specify a YouTube video and the popup to enter it would never show up
- For those without that problem, well now is a great time to turn on automatic updates for our plugin if you have the new WordPress 5.5 release. That way if a future update fixes a problem you have, then it gets installed automatically. Like robots, but in the cloud…
- Adjusted for deprecated jquery functionality
\n

2.0.15

Tested for the fresh WordPress release coming soon … WP 5.5 Codename: WFH — Stay Safe & Sane\n
- Updated testing for the latest WordPress builds so you can confidently install and get your video on
- Disclaimer: Not responsible for overconfidence or lack there of in the actual videos. That part is up to you. We believe in you though!!!
\n

2.0.14

Trimming down for speed\n
- Fixed a bug causing extra stylesheets to get included in frontend output. I mean we’re stylish, but no need for excess styling!
\n

2.0.13

Pro lovin, for our Pro Customers\n
- All of the Swarmlings: Moved lesser used options to a collapsed Advanced Options panel because everyone likes a tidy settings page, right?
- Pro Customers: Configure a watermark for your video. It can be your logo, your friends logo, or even a disco dancing dog gif if that’s your style
- Pro Customers: Looking to level up your YouTube revenue and take control of your own ads. Well we made that simple with our javascript snippet, but who wants to figure out that gobbledy gook. You are using our WordPress plugin to simplify, and now you can configure your ad platform URL directly in the plugin.
\n

2.0.12

Sometimes you need MOAR POWER\n
- You can now statically configure the Swarmify CDN key in advance from your ‘wp-config.php’ file. Just define the constant SWARMIFY_CDN_KEY and set it to your key. Config->Done
- Elementor Pro giving you heartburn when used with our widget, antacid has arrived. We worked out an issue causing Elementor Pro’s form widget to run itself out of memory.
\n

2.0.11

WordPress host wants you to upload slower, fine we can make that happen\n
- Added a toggle in the settings to disable our upload acceleration if your WordPress host has issues with it.
- We wish they would just adjust on their side, but we can be flexible so now you can turn this off in the settings if its giving your web host heartburn 😉
\n

2.0.10

Watch video faster for those who enjoy chipmunk voices\n
- Why would you want the video to play at 1.25x, 1.5x, 2x speeds? Well because you were a fan of those Chipmunk albums where you could listen to popular music sung in a high squeaky voice.
- Or it may just be your customers enjoy watching at differing paces. That must be the reason because nobody likes chipmunks, right? Alvin, alvin, ALVIN?
- All SmartVideo players now allow viewers to change the playback speed to suit their preferences.
\n

2.0.9

Too much speed!!!\n
- Some hosts weren’t ready for maximum upload acceleration so they put on the brakes and prevented media file uploads. Now we detect these slowpokes and kindly slow down from insanely fast to somewhat crazy fast upload speeds.
- If you were having trouble with uploads after previous update, that should be fixed now 😉
\n

2.0.8

Closed minded no more\n
- Display closed captions on all YouTube source videos… Or don’t. It’s up to you with a new plugin setting that enables imported captions from your YouTube videos to be shown at the click of a button. (Don’t worry, manual closed caption config is coming soon……)
- Accelerate your video uploads with new faster, better, stronger video uploading behind the scenes. Uploading videos to use in your WordPress media library will be faster and smoother than ever
\n

2.0.6

Elementary my dear Beaver\n
- Quoting for the SmartVideo widget in Elementor and Beaver Builder was not so smart. But we educated it and all of your quoting issues have been resolved.
\n

2.0.5

Oldie but goodie\n
- Fixed a bug causing WordPress versions < 4.9 to have issues with our plugin. We’re sorry Classic, you are still loved!
\n

2.0.4

Hex a Gone?: Some users have a dislike for 6 sided polygons. We are partial to them ourselves, but realize everyone has the right to the basics of life, liberty, and choice of play button shapes.
Change play button shapes:\n
- Hexagon – Our personal favorite
- Circle – For those inclined to a single side
- Rectangle – Do you like 4 sides and the golden ratio, then this is for you!
\n

2.0.3

Divi’ded we fall: If your theme colors weren’t working properly in Divi, they are now!

2.0.2

Vime ‘ode to our customers: It would be really neat if this could autoconvert all Vimeo videos like it does for YouTube, you said. Well maybe not you, but some people said this. And our answer, done! Our global autoconvert toggle now handles converting Vimeo and YouTube videos throughout your site. All without needing to get your hands dirty with any pesky template editing.

2.0.1

Classic is still cool: Fixed a bug with our Classic Editor widget where the edit window wouldn’t close when you clicked “Insert into Post”. That wasn’t very awesome at all. So we fixed it, and now our classic widget is 20% cooler.
Fixed some minor casing inconsistencies so that we can be more consistent 🙂

2.0.0

- All of the pretty native widgets you want

\n","installation":"

Deactivate and uninstall any other caching plugin you may be using. Pay special attention if you have customized the rewrite rules for fancy permalinks, have previously installed a caching plugin or have any browser caching rules as W3TC will automate management of all best practices. Also make sure wp-content/ and wp-content/uploads/ (temporarily) have 777 permissions before proceeding, e.g. in the terminal: # chmod 777 /var/www/vhosts/domain.com/httpdocs/wp-content/ using your web hosting control panel or your FTP / SSH account.
Login as an administrator to your WordPress Admin account. Using the “Add New” menu option under the “Plugins” section of the navigation, you can either search for: w3 total cache or if you’ve downloaded the plugin already, click the “Upload” link, find the .zip file you download and then click “Install Now”. Or you can unzip and FTP upload the plugin to your plugins directory (wp-content/plugins/). In either case, when done wp-content/plugins/w3-total-cache/ should exist.
Locate and activate the plugin on the “Plugins” page. Page caching will automatically be running in basic mode. Set the permissions of wp-content and wp-content/uploads back to 755, e.g. in the terminal: # chmod 755 /var/www/vhosts/domain.com/httpdocs/wp-content/.
Now click the “Settings” link to proceed to the “General Settings” tab; in most cases, “disk enhanced” mode for page cache is a “good” starting point.
The “Compatibility mode” option found in the advanced section of the “Page Cache Settings” tab will enable functionality that optimizes the interoperablity of caching with WordPress, is disabled by default, but highly recommended. Years of testing in hundreds of thousands of installations have helped us learn how to make caching behave well with WordPress. The tradeoff is that disk enhanced page cache performance under load tests will be decreased by ~20% at scale.
Recommended: On the “Minify Settings” tab, all of the recommended settings are preset. If auto mode causes issues with your web site’s layout, switch to manual mode and use the help button to simplify discovery of your CSS and JS files and groups. Pay close attention to the method and location of your JS group embeddings. See the plugin’s FAQ for more information on usage.
Recommended: On the “Browser Cache” tab, HTTP compression is enabled by default. Make sure to enable other options to suit your goals.
Recommended: If you already have a content delivery network (CDN) provider, proceed to the “Content Delivery Network” tab and populate the fields and set your preferences. If you do not use the Media Library, you will need to import your images etc into the default locations. Use the Media Library Import Tool on the “Content Delivery Network” tab to perform this task. If you do not have a CDN provider, you can still improve your site’s performance using the “Self-hosted” method. On your own server, create a subdomain and matching DNS Zone record; e.g. static.domain.com and configure FTP options on the “Content Delivery Network” tab accordingly. Be sure to FTP upload the appropriate files, using the available upload buttons.
Optional: On the “Database Cache” tab, the recommended settings are preset. If using a shared hosting account use the “disk” method with caution, the response time of the disk may not be fast enough, so this option is disabled by default. Try object caching instead for shared hosting.
Optional: On the “Object Cache” tab, all of the recommended settings are preset. If using a shared hosting account use the “disk” method with caution, the response time of the disk may not be fast enough, so this option is disabled by default. Test this option with and without database cache to ensure that it provides a performance increase.
Optional: On the “User Agent Groups” tab, specify any user agents, like mobile phones if a mobile theme is used.

Search engines like Google, measure and factor in the speed of web sites in their ranking algorithm. When they recommend a site they want to make sure users find what they’re looking for quickly. So in effect you and Google should have the same objective.

Speed is among the most significant success factors web sites face. In fact, your site’s speed directly affects your income (revenue) — it’s a fact. Some high traffic sites conducted research and uncovered the following:

Google.com: +500 ms (speed decrease) -> -20% traffic loss [1]
Yahoo.com: +400 ms (speed decrease) -> -5-9% full-page traffic loss (visitor left before the page finished loading) [2]
Amazon.com: +100 ms (speed decrease) -> -1% sales loss [1]

A thousandth of a second is not a long time, yet the impact is quite significant. Even if you’re not a large company (or just hope to become one), a loss is still a loss. W3 Total Cache is your solution for faster websites, happier visitors and better results.

Many of the other consequences of poor performance were discovered more than a decade ago:

Lower perceived credibility (Fogg et al. 2001)
Lower perceived quality (Bouch, Kuchinsky, and Bhatti 2000)
Increased user frustration (Ceaparu et al. 2004)
Increased blood pressure (Scheirer et al. 2002)
Reduced flow rates (Novak, Hoffman, and Yung 200)
Reduced conversion rates (Akamai 2007)
Increased exit rates (Nielsen 2000)
Are perceived as less interesting (Ramsay, Barbesi, and Preece 1998)
Are perceived as less attractive (Skadberg and Kimmel 2004)

There are a number of resources that have been documenting the role of performance in success on the web, W3 Total Cache exists to give you a framework to tune your application or site without having to do years of research.

\nWhy is W3 Total Cache better than other caching solutions?\n\n

It’s a complete framework. Most cache plugins available do a great job at achieving a couple of performance gains. Total Cache is different because it remedies numerous performance reducing aspects of any web site. It goes farther than the basics, beyond merely reducing CPU usage (load) or bandwidth consumption for HTML pages. Equally important, the plugin requires no theme modifications, modifications to your .htaccess (mod_rewrite rules) or programming compromises to get started. Most importantly, it’s the only plugin designed to optimize all practical hosting environments small or large. The options are many and setup is easy.

\nI’ve never heard of any of this stuff; my site is fine, no one complains about the speed. Why should I install this?\n\n

Rarely do readers take the time to complain. They typically just stop browsing earlier than you’d prefer and may not return altogether. This is the only plugin specifically designed to make sure that all aspects of your site are as fast as possible. Google is placing more emphasis on the speed of a site as a factor in rankings; this plugin helps with that too.

It’s in every web site owner’s best interest is to make sure that the performance of your site is not hindering its success.

\nWhich WordPress versions are supported?\n\n

To use all features in the suite, a minimum of version WordPress 5.3 with PHP 7.2.5 is required. Earlier versions will benefit from our Media Library Importer to get them back on the upgrade path and into a CDN of their choosing.

\nWhy doesn’t minify work for me?\n\n

Great question. W3 Total Cache uses several open source tools to attempt to combine and optimize CSS, JavaScript and HTML etc. Unfortunately some trial and error is required on the part of developers is required to make sure that their code can be successfully minified with the various libraries W3 Total Cache supports. Even still, if developers do test their code thoroughly, they cannot be sure that interoperability with other code your site may have. This fault does not lie with any single party here, because there are thousands of plugins and theme combinations that a given site can have, there are millions of possible combinations of CSS, JavaScript etc.

A good rule of thumb is to try auto mode, work with a developer to identify the code that is not compatible and start with combine only mode (the safest optimization) and increase the optimization to the point just before functionality (JavaScript) or user interface / layout (CSS) breaks in your site.

We’re always working to make this more simple and straight forward in future releases, but this is not an undertaking we can realize on our own. When you find a plugin, theme or file that is not compatible with minification reach out to the developer and ask them either to provide a minified version with their distribution or otherwise make sure their code is minification-friendly.

\nWhat about comments? Does the plugin slow down the rate at which comments appear?\n\n

On the contrary, as with any other action a user can perform on a site, faster performance will encourage more of it. The cache is so quickly rebuilt in memory that it’s no trouble to show visitors the most current version of a post that’s experiencing Digg, Slashdot, Drudge Report, Yahoo Buzz or Twitter effect.

\nWill the plugin interfere with other plugins or widgets?\n\n

No, on the contrary if you use the minify settings you will improve their performance by several times.

\nDoes this plugin work with WordPress in network mode?\n\n

Indeed it does.

\nDoes this plugin work with BuddyPress (bbPress)?\n\n

Yes.

\nWill this plugin speed up WP Admin?\n\n

Yes, indirectly – if you have a lot of bloggers working with you, you will find that it feels like you have a server dedicated only to WP Admin once this plugin is enabled; the result, increased productivity.

\nWhich web servers do you support?\n\n

We are aware of no incompatibilities with apache 1.3+, nginx 0.7+, IIS 5+ or litespeed 4.0.2+. If there’s a web server you feel we should be actively testing (e.g. lighttpd), we’re interested in hearing.

\nIs this plugin server cluster and load balancer friendly?\n\n

Yes, built from the ground up with scale and current hosting paradigms in mind.

\nWhat is the purpose of the “Media Library Import” tool and how do I use it?\n\n

The media library import tool is for old or “messy” WordPress installations that have attachments (images etc in posts or pages) scattered about the web server or “hot linked” to 3rd party sites instead of properly using the media library.

The tool will scan your posts and pages for the cases above and copy them to your media library, update your posts to use the link addresses and produce a .htaccess file containing the list of of permanent redirects, so search engines can find the files in their new location.

You should backup your database before performing this operation.

\nHow do I find the JS and CSS to optimize (minify) them with this plugin?\n\n

Use the “Help” button available on the Minify settings tab. Once open, the tool will look for and populate the CSS and JS files used in each template of the site for the active theme. To then add a file to the minify settings, click the checkbox next to that file. The embed location of JS files can also be specified to improve page render performance. Minify settings for all installed themes can be managed from the tool as well by selecting the theme from the drop down menu. Once done configuring minify settings, click the apply and close button, then save settings in the Minify settings tab.

\nI don’t understand what a CDN has to do with caching, that’s completely different, no?\n\n

Technically no, a CDN is a high performance cache that stores static assets (your theme files, media library etc) in various locations throughout the world in order to provide low latency access to them by readers in those regions. Use Total Cache to accelerate your site by putting your content closer to your users with our many CDN integrations including Cloudflare, StackPath, AWS and more.

\nHow do I use an Origin Pull (Mirror) CDN?\n\n

Login to your CDN providers control panel or account management area. Following any set up steps they provide, create a new “pull zone” or “bucket” for your site’s domain name. If there’s a set up wizard or any troubleshooting tips your provider offers, be sure to review them. In the CDN tab of the plugin, enter the hostname your CDN provider provided in the “replace site’s hostname with” field. You should always do a quick check by opening a test file from the CDN hostname, e.g. http://cdn.domain.com/favicon.ico. Troubleshoot with your CDN provider until this test is successful.

Now go to the General tab and click the checkbox and save the settings to enable CDN functionality and empty the cache for the changes to take effect.

\nHow do I configure Amazon Simple Storage Service (Amazon S3) or Amazon CloudFront as my CDN?\n\n

First create an S3 account (unless using origin pull); it may take several hours for your account credentials to be functional. Next, you need to obtain your “Access key ID” and “Secret key” from the “Access Credentials” section of the “Security Credentials” page of “My Account.” Make sure the status is “active.” Next, make sure that “Amazon Simple Storage Service (Amazon S3)” is the selected “CDN type” on the “General Settings” tab, then save the changes. Now on the “Content Delivery Network Settings” tab enter your “Access key,” “Secret key” and enter a name (avoid special characters and spaces) for your bucket in the “Create a bucket” field by clicking the button of the same name. If using an existing bucket simply specify the bucket name in the “Bucket” field. Click the “Test S3 Upload” button and make sure that the test is successful, if not check your settings and try again. Save your settings.

Unless you wish to use CloudFront, you’re almost done, skip to the next paragraph if you’re using CloudFront. Go to the “General Settings” tab and click the “Enable” checkbox and save the settings to enable CDN functionality. Empty the cache for the changes to take effect. If preview mode is active you will need to “deploy” your changes for them to take effect.

To use CloudFront, perform all of the steps above, except select the “Amazon CloudFront” “CDN type” in the “Content Delivery Network” section of the “General Settings” tab. When creating a new bucket, the distribution ID will automatically be populated. Otherwise, proceed to the AWS Management Console and create a new distribution: select the S3 Bucket you created earlier as the “Origin,” enter a CNAME if you wish to add one or more to your DNS Zone. Make sure that “Distribution Status” is enabled and “State” is deployed. Now on “Content Delivery Network” tab of the plugin, copy the subdomain found in the AWS Management Console and enter the CNAME used for the distribution in the “CNAME” field.

You may optionally, specify up to 10 hostnames to use rather than the default hostname, doing so will improve the render performance of your site’s pages. Additional hostnames should also be specified in the settings for the distribution you’re using in the AWS Management Console.

Now go to the General tab and click the “Enable” checkbox and save the settings to enable CDN functionality and empty the cache for the changes to take effect. If preview mode is active you will need to “deploy” your changes for them to take effect.

\nHow do I configure Rackspace Cloud Files as my CDN?\n\n

First create an account. Next, in the “Content Delivery Network” section of the “General Settings” tab, select Rackspace Cloud Files as the “CDN Type.” Now, in the “Configuration” section of the “Content Delivery Network” tab, enter the “Username” and “API key” associated with your account (found in the API Access section of the rackspace cloud control panel) in the respective fields. Next enter a name for the container to use (avoid special characters and spaces). If the operation is successful, the container’s ID will automatically appear in the “Replace site’s hostname with” field. You may optionally, specify the container name and container ID of an existing container if you wish. Click the “Test Cloud Files Upload” button and make sure that the test is successful, if not check your settings and try again. Save your settings. You’re now ready to export your media library, theme and any other files to the CDN.

You may optionally, specify up to 10 hostnames to use rather than the default hostname, doing so will improve the render performance of your site’s pages.

\nWhat is the purpose of the “modify attachment URLs” button?\n\n

If the domain name of your site has changed, this tool is useful in updating your posts and pages to use the current addresses. For example, if your site used to be www.domain.com, and you decided to change it to domain.com, the result would either be many “broken” images or many unnecessary redirects (which slow down the visitor’s browsing experience). You can use this tool to correct this and similar cases. Correcting the URLs of your images also allows the plugin to do a better job of determining which images are actually hosted with the CDN.

As always, it never hurts to back up your database first.

\nIs this plugin comptatible with TDO Mini Forms?\n\n

Captcha and recaptcha will work fine, however you will need to prevent any pages with forms from being cached. Add the page’s URI to the “Never cache the following pages” box on the Page Cache Settings tab.

\nIs this plugin comptatible with GD Star Rating?\n\n

Yes. Follow these steps:

Enable dynamic loading of ratings by checking GD Star Rating -> Settings -> Features “Cache support option”
If Database cache enabled in W3 Total Cache add wp_gdsr to “Ignored query stems” field in the Database Cache settings tab, otherwise ratings will not updated after voting
Empty all caches

\nI see garbage characters instead of the normal web site, what’s going on here?\n\n

If a theme or it’s files use the call php_flush() or function flush() that will interfere with the plugins normal operation; making the plugin send cached files before essential operations have finished. The flush() call is no longer necessary and should be removed.

\nHow do I cache only the home page?\n\n

Add /.+ to page cache “Never cache the following pages” option on the page cache settings tab.

\nI’m getting blank pages or 500 error codes when trying to upgrade on WordPress in network mode\n\n

First, make sure the plugin is not active (disabled) network-wide. Then make sure it’s deactivated network-wide. Now you should be able to successful upgrade without breaking your site.

\nA notification about file owner appears along with an FTP form, how can I resolve this?\n\n

The plugin uses WordPress FileSystem functionality to write to files. It checks if the file owner, file owner group of created files match process owner. If this is not the case it cannot write or modify files.

Typically, you should tell your web host about the permission issue and they should be able to resolve it.

You can however try adding define(‘FS_METHOD’, ‘direct’); to wp-config.php to circumvent the file and folder checks.

\nDoes the WebP Converter extension use a lot of resources to convert images to WebP?\n\n

No. The WebP Converter extension converts common image file formats to the modern WebP format using our API services. The conversions occur on our API service, so that resource usage does not impact your website server.

\nIs image data retained by the Total Cache WebP Converter API?\n\n

Image data received by our API is destroyed after a converted image is generated. The converted iamges are destroyed once picked-up/downloaded to your website by the Total Cache plugin.

\nThis is too good to be true, how can I test the results?\n\n

You will be able to see the results instantly on each page load, but for tangible metrics, you should consider using the following tools:

Google PageSpeed
Google Search Console Core Web Vitals Report
WebPagetest
Pingdom
GTmetrix

\nI don’t have time to deal with this, but I know I need it. Will you help me?\n\n

Yes! Please reach out to us and we’ll get you acclimated so you can “set it and forget it.”
