Support » Plugin: Query Monitor » Invalid Argument Error when plugin is disabled or deleted

  • safetypros


    I need to disable/delete this plugin because it is conflicting with others (I think). In order to test it I need to disable and/or delete it. When I tried this both result in this error:

    Warning: Invalid argument class-wp-list-util.php. on line 150

    Currently, I have it installed and disabled to get around this error. I am trying this on a Siteground staging copy of my site. Please provide a fix for this immediately.

    Sorry to hear you’re having problems. Can you deactivate other plugins on your site? Is the problem specific to QM?
