Cannot delete the Plugin

Hi @markzoi, I’m sorry you’re experiencing an error. Could you tell me what error you’re seeing?

If you want to uninstall the plugin without going through WordPress, you could also delete the plugin files, which you can do through the interface you’re hosting provider provides. You would need to delete the files in the wp-content/plugins/matomo directory.

Thanks for your replay, yes Deletion worked via FTP … this was the message: deletion failed. A critical error has occurred on the website. Learn about WordPress troubleshooting.

Bye, Mark

@markzoi Sorry, I was asking about the error you saw before trying to delete the plugin. If possible, we’d like to know what the error was so we can try and fix it.

Hi this is the only message I got it, no error number nothing … I translate the message but that’s it ?? I hope It help …

@markzoi I see, in that case the real error message will be in the PHP error logs. If you are willing to look for them, we’d certainly appreciate it, but since your immediate issue is resolved, it’s understandable if you don’t want to spend more time on this. For now I’ll mark this issue as resolved (you’ll still be able to comment here, though).

It’s ok the problem is solved by deleting via ftp. Thank you for you help

In case this helps, we had the same issue (cannot delete plugin) and the PHP error log provided this:

When removing all plugins and reverting to the TwentyTwentyFive theme, we still were unable to delete the plugin. Maybe this error code above can help narrow down where this issue might come from? Fortunately we restored from backups to avoid extraneous data being left in the database.

@ac2a Yes, that’s very helpful, thanks. We should be able to fix this issue in the next version with that information.
