Gatekeeper allows administrators to take a WordPress site offline quickly and easily while leaving it fully accessible to administrators and other authorized users. Site visitors will be shown or redirected to a specified offline page. An optional blacklist can be used for permanent bans.
** Features **
- Visitors can either be redirected to an existing non-WordPress offline page (using http 302 temporary redirect) or WordPress pages can be temporarily replaced with the offline page.
- Logged in admins can be whitelisted
- The current admin’s IP address can be automatically whitelisted
- An IP-based whitelist that can accept specific IP addresses, wildcards, and ranges
- A basic IP-based blacklist that redirects blacklisted IPs to a specified page (not to be used for security)
- A notifier that appears on administrator pages when the site is offline
