Blank boxes

When we try to access FluentCRM Pro sections and click on Contacts, Campaigns, and Automations, they are all loading as blank screens. The same issue is happening with Campaigns and Automations; they just all appear blank.

Basically, there is an empty box taking up the whole screen, pushing the rest off. Those boxes appear to be the irritating notices from plugins we always get: Auto Advance for Gravity, BuddyBoss, and possibly others.

It appears that Fluent is trying and failing to get rid of those boxes. Basically, it is suppressing the boxes, but not fully, so the boxes still appear, but they are empty and broken.

Ideas?
