    Hi, do you know if you set up our plugin correctly? Are all your other plugins up to date? What happens if you disable our plugin? Do you still see that error message?

    Can you also test one of WordPress default themes like Twenty Seventeen while our plugin is active? This is just for testing purposes.

    Regards
