Today we discovered an issue in currently up-to-date WordPress sites (5.8) with DIVI 4.10.2 – this broke some special functionality of some plugins that rely on jQuery and jQuery migrate.

The console showed javascript jquery errors and also a warning soon after:

After extensive testing and process of elimination, we found that the DIVI Performance setting for “Defer JQuery and jQuery Migrate” was causing the issue:

Fix for DIVI JQuery Migrate Issues

Once turned off, purge the site cache and test again to see if the issues are resolved.
