Automatically purge every server-side cache on your WordPress site — plugins, hosting environments, PHP, memory stores, and CDNs — all from one place.

Kevin Pirnie

The Cache Purger takes the headache out of cache management. Instead of juggling a dozen different cache-clearing buttons across your stack, this plugin hooks into WordPress actions and fires them all at once — automatically, on a schedule, or with a single click from the admin bar.
It covers the full spectrum: popular caching plugins, managed hosting environments, PHP-level caches (OPcache, APC, WinCache), server-level caches (Nginx, Varnish, PageSpeed), in-memory stores (Redis, Memcache, Memcached), and external CDN/WAF APIs (Cloudflare, Sucuri, Fastly).
Every purge is configurable. Choose which cache types to include, which WordPress events should trigger a purge, and which specific posts, pages, CPTs, or field groups to exclude. You can also run purges on a WP Cron schedule, or kick one off manually via WP-CLI.
<h4>What Gets Purged</h4>
Caching Plugins
Flying Press, SiteGround Optimizer, Nginx Helper, LiteSpeed Cache, Cachify, Autoptimize, Fast Velocity Minify, WP Rocket, Swift Performance, Comet Cache, Hummingbird, WP Fastest Cache, WP Super Cache, W3 Total Cache, Hyper Cache, WP-Optimize, Cache Enabler, NitroPack, Divi, Elementor, WP REST Cache, and more.
Hosting Environments

<h4>Purge Triggers</h4>
Configure purges to fire automatically on any combination of the following WordPress events:
<ul>
<li>Post save / update / trash</li>
<li>Page save / update / trash</li>
<li>Custom Post Type save / update / trash</li>
<li>Taxonomy / term save / delete</li>
<li>Category save / delete</li>
<li>Menu save / delete</li>
<li>Widget save / delete</li>
<li>Customizer save</li>
<li>GravityForms form save / trash (requires GravityForms)</li>
<li>Advanced Custom Fields field group save / trash (requires ACF)</li>

<li>Plugin activation / deactivation</li>
<li>Core / plugin / theme updates</li>
<li>Plugin settings save (this plugin’s own settings page)</li>
</ul>
Exclusion lists are available for posts, pages, CPTs, GravityForms forms, and ACF field groups — so you can carve out anything that shouldn’t trigger a purge.
<h4>Additional Features</h4>
<ul>
<li>Admin bar button — Master Cache Purge available on every admin page, one click from anywhere.</li>
<li>Purge log — Optional logging of every purge action to <code>wp-content/purge.log</code>, viewable directly in the settings UI with a one-click clear.</li>
