@danbp, I just realized that my request is a bit out of scope. Actually I would need a widget that would show “My Groups” rather than “Newest/Active/Popular Groups”, so I will try to search for another widget and eventually I will try to create it. Thanks for your explanation.
@danbp, thank you for your explanation. I thought that “hidden group” means hidden for other users outside the group, for public group lists etc. I still don’t understand, why the “hidden group” should be hidden also for it’s own members.
I can confirm that I have the same issue. Admin users can see all groups, including the hidden groups, but the hidden groups are invisible for regular members in the BP Groups Widget.
