Hello JoomlaPraise,
First off thank you for continuing work on the Project Fork module! It's really very good

However, since the latest update to 2.0.12 we're suffering from a strange bug, our users are unable to modify their user groups.
If they add or remove a member from a project group, they get a 'Not Authorised' error. They can however, remove the entire group and rebuild it from scratch.
But modifying an already existing group proves troublesome.
I'm a bit stumped to what the solution might be, so any help you can provide would be most appreciated.
If you need more information, please ask

Thanks in advance!
