There is a thread which is hidden in forum view. But I'm still able to post in it and it's shown in latest reply on forum home. It's the thread "Use IPGallery for xenForo". I'm able to access it through my profile. If you deleted the thread I shouldn't be able to access it. If you hid it, it shouldn't be shown in last post on forum home. There are users in this thread who I ignore. Perhaps it's related to that.
