I'm having a quite annoying problem with my XenForo installation (Latest 1.1.1). I also had this problem before on the earlier 1.1.0 I think it was. People will be browsing my forums then it will say that they have been IP banned from the forums, but if they clear their cache it seems to work fine again. I'm not sure what's causing this and I've found noone with this issue. The people aren't actually IP banned and their not in the Admin CP, but it gives them the notice and they can't browse for about an hour. Any help with this?
