I was unable to locate where in the settings this is handled, and I guess I couldn't find the right search terms because Google wasn't any help with this. If someone could explain where these settings are I'd be greatly appreciative.
I also have one user who is having some very strange issues. He has a thread where if you view it and refresh the page it will log you out of xenForo. Another user came to me saying this was happening in the bugged users thread, and it was happening to me as well. I can't do anything to the post because any time I view the page I get logged out. This is most definitely not an XSS attempt as I know the bugged user and they would not do anything like that.
Any help anyone could offer with this would be appreciated, because as it is now I'm stuck and am completely at a loss for why this is only happening to one user and only that one thread does that.
