Purges all cache on WPEngine, W3 Total Cache, WP Super Cache when updating widgets or menus.
NOTE: If you do not use the W3 Total Cache or WP Super Cache plugins 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 save a widget or menu. It may be overkill, which may be why it's not built in, but some people need simplicity.
Now 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.
