Actually prevented a break on upgrade
by rubigma·5 months ago
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.
Not useful without $20/month subscription
by bhammondCVL·5 months ago
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.
A joke ?

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 ?
Plugin Compatibility Checker is Awesome!
by q120000·8 months ago
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.
