Clear Cache for Me

Purges all cache on WPEngine, W3 Total Cache, WP Super Cache, WP Fastest Cache when updating widgets, menus, settings.

NOTE: If you do not use the W3 Total Cache or WP Super Cache plugins, WP Fastest Cache, or do not host your website on WPEngine, this plugin will do nothing for you.

W3 Total Cache and WP Super Cache are great caching plugins, but they do not know when a widget is updated. WPEngine is the best place to host your WordPress installation, but their caching system is no smarter when it comes to updating widgets and menus. I created this plugin because my website did not see any changes when saving widgets or menus using these caching systems. Clear Cache For Me will purge ALL your cache each time you do a save without having to press an additional button. It may be overkill, which may be why it's not built in, but some people need simplicity.

Works with the following caching systems:

  • W3 Total Cache
  • WP Super Cache
  • WP Fastest Cache
  • WPEngine hosting

Clears all cache for following actions:

  • When Widgets are saved
  • When Customizer is saved
  • When Menus are saved
  • When Settings from a settings page is saved.
  • When a Contact Form 7 form is saved.
  • When WooThemes settings are saved.
  • When NextGen Gallery albums and galleries are updated (beta - may not clear cache on all actions).

There is a convenient clear cache button on the dashboard for users with the right capability. Admins (users with the 'manage_options' capability) can set which capability a user needs to view the button. If you are using this button often, please consider submitting a request to have this plugin do your button-pushing for you. This plugin is meant to work behind the scenes to make your life easier and less frustrating.

Developer Options


Use this filter to determine if this plugin should do anything including showing the button on the dashboard. Return true if a caching system is supported.
Default: True if any of the supported caching systems is active.
See Example 1 below.


Use this action to add hooks when cache is to be cleared. Or do any other setup activity.


Use this action to clear cache from an unsupported caching system before the default caching systems clear their cache.


Use this action to clear cache from an unsupported caching system after the default caching systems clear their cache.

Example 1

Thanks to Benjamin Pick - If you are using Autoptimize and need to clear the CSS or JS files automatically, you can add the code below to your theme's functions.php file. This code also demonstrates how you can add an unsupported caching system and have its cache cleared for you.
also pasted below:

function yt_cache_enable($return) {
    if (class_exists('autoptimizeCache'))
        return true;
    return $return;
add_filter('ccfm_supported_caching_exists', 'yt_cache_enable');

function yt_cache_clear() {
    if (class_exists('autoptimizeCache'))
add_action('ccfm_clear_cache_for_me', 'yt_cache_clear');

Example 2

Thanks to Benjamin Pick - If you have an automatic deployment setup and need a webhook to clear the caches, you can add this code to your theme's functions.php file.
also pasted below:

if (!defined('CLEAR_CACHE_HOOK_KEY'))
    define('CLEAR_CACHE_HOOK_KEY', 'some_secret_key_please');

function yt_cache_clear_web_hook() {
    if (isset($_GET['key']) && $_GET['key'] == CLEAR_CACHE_HOOK_KEY) {
        if (function_exists('ccfm_clear_cache_for_me')) {
            ccfm_clear_cache_for_me( 'ajax' );
            echo 'Cache was cleared.';
        } else {
            echo 'Install the plugin "Clear Cache For Me" first';

// Call this URL to clear the cache:
// /wp-admin/admin-ajax.php?action=clear_cache&key=some_secret_key_please

add_action( 'wp_ajax_clear_cache', 'yt_cache_clear_web_hook' );
add_action( 'wp_ajax_nopriv_clear_cache', 'yt_cache_clear_web_hook' );
