What happens if I don’t activate a license?: You must first register and activate at least the Free License to see PHP 8.4 compatibility results. Without license activation, visibility will be limited. Pro unlocks dashboard analytics, notifications and vulnerability insights.
Why does a plugin show “No Data”?: This usually means the plugin is either custom/premium or its version has been removed from WordPress.org.
Do I need to rescan after adding new plugins?: Yes, please click Rescan to include new plugins in the compatibility check.

The free version gave me a basic idea, but the paid version was way more useful. It caught PHP issues that I wouldn’t have noticed before updating. Glad I upgraded because it saved me time fixing errors later. Definitely more helpful when running sites on newer PHP versions.

The plugin will only check major-version compatibility (6, 7, 8) without paying $20/month for a service subscription. If you want to try that, go for it. The free version, though, will not tell you much that is useful.

The plugin checks in free version up to php 8.0+ compatibility. Who needs to know if a plugin is compatible with an obsolete version of php ?

PCC is very convenient when deciding to update Wordpress and PHP versions. With one click of the mouse it will provide helpful information letting you know ahead of time which plugins might cause issues of compatibility. And is especially helpful with Multisite installations that have several plugins being used with various sub-sites. Thank you Dinesh.

The plugin is a great tool I use for new clients to get an overview of versions of the installed plugins, supported WordPress versions and PHP versions before upgrading a site. Saves me time. Thanks! Easy worth 5-stars.

Hello, I like the concept of using a specific page and would use your plugin if it can also display PHP version supported by the plugins. It is an info you can find for individual plugin in WordPress.org repository but would be nice to have that for all plugins at once ! Eric Collart
