Bug /Conflict -Popup Arrow

Hello WCP Linked Variation,
I recently migrated to a Cloudways Vultr server (PHP 8 and MariaDB 10.4) and since then I am experiencing a conflict between the Wordfence and WCP Linked Variations plugin. To be more specific, the popup arrow is surrounded by a red box. If I turn off Wordfence the Popup error displays as it should. At my old hosting company (EasyWP/NameCheap) there was no conflict between the two. For this reason, I have first been in contact with Cloudways to see if the bug exists server side. However, it does not appear to be a server side issue, which is why I am now contacting you. I wonder if it could be some compatibility issue with perhaps PHP8 or the MariaDB -or something else?

If you don’t have a solution, I wonder if there is a selector for the popup arrow that I can use to hide it (ex so that only the popup shows on hover)? I have only been able to identify the selector for the popup – not the arrow.

Kind regards,
Rikke
