Thank you for the correction. Yes, this would be Group owners.
I'm still having difficulty. in the backend (and while logged in as superuser), the ability to change the status of a user status is under the "User" menu, and not "Group". If I try to change the status from Owner to Admin, I get the following error:
Error
Failed to save User because: Group owner can not be demoted!
Sreenshot attached.
In the front end (While logged in as the groups other Owner) there is no option to demote the owner. You can see it there for the moderator, but not the owner.
Screenhot attached.
Any thoughts of where or how I could be missing how to do this? Thanks for your help.
