We recently found an Active PHP Session error on our Site Health, and here is how you can identify the possible plugins causing it. Check your Site Health page — for that, go to Tools → Site Health. The error is: “An Active PHP session was detected.” If you click on it, you’ll see “A PHP session was created by a session_start function call.” If you see this error, we need to identify the plugins causing it.

For that, use our custom plugin. Go to Plugins → Add Plugin and upload the plugin. Then install and activate the plugin. Once activated, go to Tools → Find Session Start. Here you will see the plugins you need to check to resolve the issue. Deactivate each plugin one by one and check if the error goes away — if it does, then that plugin is the root cause. We hope this video was useful — Thank you very much!
