Forum Unregistered/Guests can see my forum, even though I've set permissions to "all no"
 

I've set banned, unregistered, users waiting for confirmation etc all to "all no" in the permissions page. I've disabled registrations and I do NOT want my forum to be public, or viewable by non-members.

Why is this happening? My other forum running 4.2 works just fine.

Please help!!
