I have upgradet bbPress 1.1 (standalone) to bbPress 2.4 integrated in WordPress. Some new written posts will not shown in the forum-index. In the topic-overview it shows the correct post order (post time and date). I have installed the GD bbPress Tools and when I klick on show the newest replys, the order of the topics is confused. I think there is a problem with user rights, because some posts are displayed correctly and some do not. If the administrator with id 4 writes a post, it will not display correctly. When the user id 240 (new user) writes a new post, it will shown correct.
I had searched for sich problem, but the solutions I found was for bbPress 1.
