When i try to add a user i get an error to select a category. The category box display ABGCP and does not display any existing categories.
Site is currently running on Ubuntu 18.04, PHP 7.2, MySQL 5.7.30 and CB 4.1 STABLE.
It was upgraded from Ubuntu 12.04, PHP 5, MySQL 5.5.53, and CB 2.8.1.
CB was upgraded to 2.8.2 then 2.8.3 then OS was upgraded to 18.04. Then CB was upgraded to 4.0 and then 4.1. Everything else is working. It appears to only be an issue with the user categories.
Update - 05/06/2020
I upgrade MySQL to 8.0.20 - Still same issue with the user category.
Upgraded site to 4.2 RC1 - Still same issue with the user category.
Everything else is still working except for adding users.
Thanks for any help.
