I have a problem with my Cornerstone Plugin. It produces a huge error message in the header of the wordpress dashboard and the website. Could you please help me with that? I already updated wordpress, all the plugins, deactivated the plugins and the error keeps on coming up when activating Cornerstone (version 5.3.3). There is no possibility to update any further.

Thanks for your support!
