I have a private group with private content which I set up with group visibility and group content visibility. Logged in as a non-member of this group I get access denied on the group page however when I enter the url of a node within that group I can see it fine.
I am using views cloned from the original OG views and I even tested it with the OG views and it is still allowing a non-member to see the nodes.
I have also rebuilt permissions a number of times.
I am unsure whether this is a bug in OG or a problem with my settings?
