I gave the Role bp_moderate but that did not solve the issue. There must be some other check that needs to be passed for these menu items to show up.
Maybe a compromise could be found and some new functionality for the front end could be introduced that allows you to assign someone as Group Admin. I think i am not the only one that sees value in that Role especially in a big community where you have the need to moderate but do not want to give people access to the backend or higher Administrative privileges.
I also don’t quite understand why a Group admin could not be derived from one of the Forum Roles. A forum Moderator or Keymaster should be able to moderate all Forums incl. the private group ones and could subsequently also be allowed to manage all groups.
That is not the answer i was looking for. If you have to design groups and capabilities in a non wordpress standard way then at least offer some way to control this mess. What a huge disappointment this is. Maybe the developers need to go back to the drawing board.
