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:
One-Click Cache Clearing: Clears multiple cache layers across WordPress, server, and browser.
Individual Clear Actions: Run specific cache clearing actions independently.
Admin Bar Access: Quick purge button in the WordPress admin bar (eraser icon).
Hosting Integration: Supports clearing hosting-level cache via configurable purge URL.
Third-Party Support: Clears cache for supported plugins and services.
Detailed Logging: Logs execution time for each action.
Developer Hooks: Add additional cache clearing actions via developer hooks.
The following clearing actions are available:
Rewrite Rules – Flushes WordPress rewrite rules so permalink and routing changes apply immediately.
WordPress Object Cache – Clears the in-memory object cache used to store database query results.
Transients – Deletes all transients, forcing temporary data to regenerate on next load.
OPcache Reset – Resets PHP OPcache so compiled scripts reload from disk.
APCu Cache – Clears the APCu user cache, a PHP data cache separate from OPcache.
Varnish Cache – Sends a purge request to Varnish to invalidate reverse proxy cached pages.
Redis / Memcached – Flushes persistent object cache if Redis or Memcached is active.
Fragment Cache – Clears cached template fragments generated by themes or plugins.
REST API Cache – Removes cached REST responses to ensure endpoints return fresh data.
Sessions – Destroys active PHP sessions. Users may need to log in again.
Cookies – Removes site-related browser cookies set by WordPress or plugins.
Browser Cache – Forces browsers to revalidate and reload cached static assets.
Hosting Cache – Triggers a configured purge endpoint to clear host-level caching.
Cloudflare Cache – Purges all Cloudflare-cached content via the Cloudflare API.
Generic CDN Cache – Purges cache via a configured CDN endpoint and API key.

FAQ
How does this plugin clear cache?
It executes multiple cache-clearing actions across WordPress core, object caching systems, server-level caching, browser cache, and supported third-party plugins. Individual actions can be triggered independently.
Why does it take so long to clear the cache sometimes?
Clearing cache is not just a single action. When you click “Clear All,” the plugin may be flushing multiple cache layers: object cache, persistent cache (Redis/Memcached), OPcache, reverse proxies like Varnish, REST caches, transients, sessions, and third-party integrations. Each layer operates differently and may require disk I/O, memory resets, or network requests. On larger sites, clearing cache can take longer because: • Persistent object caches may contain thousands of keys that must be invalidated. • OPcache must reload compiled PHP scripts into memory. • Reverse proxies and CDNs require network-based purge requests. • Transients and fragment caches may involve large amounts of stored data. After cache is cleared, the site must rebuild it. Themes and plugins will: • Re-run expensive database queries. • Recompile templates. • Regenerate CSS/JS assets. • Rebuild REST responses. • Recreate transients and computed data. This recaching happens on the next page load and can temporarily slow down the first request after a purge. That is expected behavior. If you find that clearing everything takes longer than you prefer, certain actions (such as Transients) can be disabled from the “Clear All” button and admin bar in the settings. They can still be cleared independently from the settings page when needed. In some cases, you may not need to clear every layer. For example, content edits typically do not require transients or OPcache to be reset. Selectively clearing only what is necessary can significantly reduce execution time.
Does this work with all hosting providers?
This depends on your hosting provider. If they offer a cache purge URL, you can configure it in the plugin settings. For example, if you have GoDaddy's Website Security and Backups, you can navigate to Firewall > Settings > Performance > Clear Cache, then grab the Clear Cache API link to put in your settings.
Will this force browsers to load fresh content?
Yes! The plugin sends cache-control headers to prompt browsers to reload updated content.
Can I add custom cache clearing actions?
Yes. Developers can hook into the clearing process to add custom actions or settings. Full developer documentation is available here: https://pluginrx.com/docs/plugin/clear-cache-everywhere/
Is there a function to trigger clearing cache everywhere?
Yes! A helper function is available for you to use: cceverywhere_clear_all( $log_results = false ). The function returns the results of the cache clearing processing. Optionally, you can log the results by setting the $log_results parameter to true. This will log the results to the debug log.
Where can I request features and get further support?
We recommend using our website support forum as the primary method for requesting features and getting help. You can also reach out via our Discord support server or the WordPress.org support forum, but please note that WordPress.org doesn’t always notify us of new posts, so it’s not ideal for time-sensitive issues.
Installation
1. Upload the plugin files to the /wp-content/plugins/clear-cache-everywhere/ directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.
3. The Clear Cache button will appear in the admin bar.
Fix: Nginx Helper integration was calling a non-existent function; now uses the correct `rt_nginx_helper_purge_all` action hook
Fix: Hummingbird integration used `function_exists()` on a class method, which never evaluates true; now uses `method_exists()`
Update: Added Breeze, NitroPack, and Pantheon Advanced Page Cache existence guards to their clearing methods and settings field registration
Update: Added Cache Enabler, SpinupWP, Cachify, Powered Cache, Rocket.net, Object Cache Pro, and WP Cloudflare Super Page Cache integrations
Update: Added generic CDN purge action (purge URL + API key) for CDNs without a dedicated integration
Update: All integration settings fields now verify the target plugin's function/class/hook actually exists before displaying, in addition to `is_plugin_active()`, so unverified or version-mismatched integrations no longer surface as failing checkboxes
1.2.2.1
Fix: Cornerstone integration wasn't working on X Theme Pro
1.2.2
Fix: `cceverywhere_clear_all()` helper function now correctly supports the `$log_results` parameter
Fix: Custom callbacks on page-context actions now fire correctly
Fix: Hummingbird cache detection now uses `method_exists()` instead of `function_exists()`
Fix: Added capability check to `clear_all()` for requests coming through the URL parameter
Fix: Auth cookies `wordpress_sec_*` and `wp-settings-*` are now preserved when clearing cookies
Fix: Removed invalid `href` attribute from Clear Cache button on settings page
Performance: `get_clearing_actions()` now caches its result to avoid redundant calls per request
Developer: Added `cceverywhere_clearing_actions` filter to allow modifying the actions array programmatically
Update: Clarified readme description of available clearing actions
