I just installed Drupal Commons 7.x-3.x. I configured two private groups, and added a normal user to them. That user can see content posted to those groups, but it cannot see the group itself, or post content to the group.
Why?
I've added the user as an administrator in the group.
I've cleared all the Drupal Caches on the performance page.
I've cleared my browsers cache.
I've logged the user in and out.
I've rebuilt node permissions.
I've run cron manually.
I've double checked the people/permissions to make sure the user had permission to create groups, just in case that mattered.
No matter what I do, if I try to go to commons/groups/privategroupname with my non-user1 user I get an "Access Denied" page.
If the user wasn't a member, it would not be able to see the content in the list on the /home page.
Public groups work fine.
When creating the private groups, I selected: "Joining requires an invitation. The group and content is hidden from non-members." in the Privacy Settings.
So, I'm at a loss. Help!
