ramsey1971 As mentioned in the previous posts, the changes need to be made in the following file:
[root]/plugins/system/t4/themes/base/html/com_config/modules/default.php
However, I checked this file on your site and noticed that the modification was missing — it seems the T4 plugin was reinstalled, which overwrote the file and caused the issue to reappear.
I’ve reapplied the update, and the frontend module editing is now working properly again 😉
