Hello, I was having trouble deleting group categories. See video https://app.screencast.com/GJJGyyohaUWug
I reported this to the dev that helps me out and he wrote this
I fixed this issue.
I modified the file: administrator/components/com_community/views/groupcategories/tmpl/default.php
Replace the code line:
submitform(action);
To:
Joomla.submitform(action);
You can report JoomSocial team to apply this fix to the next release.
It fixed the issue only the modal window does not pop down confirming the action.
