  • A must before updating to a new PHP version

    My Wordpress was using a very old version of PHP and I kept getting warnings that I soon would not be able to upgrade Wordpress any longer because my version of PHP would no longer be supported. I wanted to make sure that all my plugins would be compatible with PHP 8.3 because I didn't want the PHP upgrade to somehow break my site. I paid the reasonable $1 that the Compatibility Checker asked for a monthly subscription, and it noted which of my plugins were not supported. I removed them and had a successful upgrade to PHP 8.3 without breaking my site. The support folks for this plugin respond instantly in their webchat when I had questions.

  • Excellent Plugin

    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.

  • Actually prevented a break on upgrade

    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

    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 ?
