I have a similar problem to the one described here:
https://simple-press.com/support-forum/sp5-general-topics/problem-since-upgrade-to-5-1-3/
My forum is setup here:
http://www.interactbuilder.com/forum
My forums are setup to be available to guests and to members, but right now nobody can see the forums. You will see on the page it says:
The requested group does not exist or you do not have permission to view it
I tried resetting my cache but this hasn’t helped either. Looks like there’s a problem with permission sets. I clicked on Manage Permission sets and there are some duplicate entries. Please see enclosed screen shot.
Please help, I’m not sure what to try next.
