For some unknown reason, the Merge topics function starting return the error:

“There has been a critical error on your website”

“Learn more about debugging in WordPress”

So I setup a staging site and disabled all of the plugins and started re-activating them one-by-one. With everything deactivated the Merge topics button worked just fine. You could see the dropdown box with all of the available topics to choose from.

I got down to the last major plugins, “Paid Memberships Pro” and “Business Directory Plugin” and when I activate either one of these, the Merge topic button returns the “There has been a critical error on your website” message.

We are running WordPress version 5.4.2, PHP version 7.0.33 and bbPress version 2.6.5

Any suggestions on possible fixes or quick ways to troubleshoot further will be greatly appreciated!
