Great Tool for Troubleshooting

Incredibly useful for developers / support staff / agencies to get useful debug info from clients. 

Fantastic Troubleshooting Tool

Just stumbled on this today. Absolutely love how simple it is. The bonus ability to email the info directly, or post a public link is really excellent. Thanks for creating this and making it available to the community at large!

(Full Disclosure:) I loved this plugin so much, and I noticed it wasn't being maintained, so I adopted it and am now maintaining it.

Plugin Compatibility Checker

very helpful to check our plugin compatibility


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 ?


A joke ?


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.


Actually prevented a break on upgrade

Scan and check your plugins for PHP and WordPress compatibility. Requires a $1/month Portal subscription to obtain a license key.
