I log in to howtoforge, and go to "New posts". it shows me I clicked through most of the forums, and indeed there were no new posts unread by me. But it looks like posts from past few days in ISPConfig Priority Support -forum are unread and not shown in new posts. I can see them when I click to Priority Support forum. Is this a bug or feature?
It might be that the new posts function in Xenforo does not include posts that are in a forum that is not visible to the public.
