What Users Are Saying
Real reviews from WordPress developers and site owners.
"This is a fantastic plugin that saves a lot of time and prevents problems during version upgrades to PHP and also Wordpress itself. We can highly recommend it and it is worth the optional paid subscription."
"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."
"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."
"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."
