Clear Cache Everywhere allows administrators to instantly clear various cache sources directly from the WordPress admin bar. This ensures changes are reflected immediately without waiting for cache expiration.
Features:
<ul>
<li>One-Click Cache Clearing: Clears multiple cache layers across WordPress, server, and browser.</li>
<li>Individual Clear Actions: Run specific cache clearing actions independently.</li>
<li>Admin Bar Access: Quick purge button in the WordPress admin bar (eraser icon).</li>
<li>Hosting Integration: Supports clearing hosting-level cache via configurable purge URL.</li>
<li>Third-Party Support: Clears cache for supported plugins and services.</li>
<li>Detailed Logging: Logs execution time for each action.</li>
<li>Developer Hooks: Add additional cache clearing actions via developer hooks.</li>
</ul>
By default, clearing the cache will execute the following actions:
<ul>
<li>Rewrite Rules – Flushes WordPress rewrite rules so permalink and routing changes apply immediately.</li>
<li>WordPress Object Cache – Clears the in-memory object cache used to store database query results.</li>
<li>Transients – Deletes all transients, forcing temporary data to regenerate on next load.</li>
<li>OPcache Reset – Resets PHP OPcache so compiled scripts reload from disk.</li>
<li>Varnish Cache – Sends a purge request to Varnish to invalidate reverse proxy cached pages.</li>
<li>Redis / Memcached – Flushes persistent object cache if Redis or Memcached is active.</li>
<li>Fragment Cache – Clears cached template fragments generated by themes or plugins.</li>
<li>REST API Cache – Removes cached REST responses to ensure endpoints return fresh data.</li>
<li>Sessions – Destroys active PHP sessions. Users may need to log in again.</li>
<li>Cookies – Removes site-related browser cookies set by WordPress or plugins.</li>
<li>Browser Cache – Forces browsers to revalidate and reload cached static assets.</li>
<li>Hosting Cache – Triggers a configured purge endpoint to clear host-level caching.</li>
</ul>

This is a beta release. If anything breaks, SORRY! Drop me a note to report a bug.
Provides an admin interface for inspecting Memcached instances and flushing items by key or group in an AJAX fashion. This should be considered a pre-release beta be-super-careful-when-using-type release.
I’ll be updating this plugin a lot soon.
