Thanks to user Lewpy it came to my attention, that registered users couldn’t post in the new forum. For some reason registered users had fewer rights than newly registered users, which were disabled by default. All registered user should now be able to post new topics and replies as well.

After struggling with all the disadvantages of bbPress and constantly broken permalinks I have decided to switch to phpBB3 for the new support forum. The link to the new forum is http://www.alexpage.de/forum/. The old forum will still be accessible for a while. I will move all relevant content to either the FAQ or the new forum. The rest including the old forum users will be deleted afterwards. For now the link to the old forum is http://www.alexpage.de/forums/forum.php?id=2.

Because it became more difficult to reply on feedback and error messages just by the WordPress comment function, I have setup a small forum for support questions. I would like you to ask questions there, because it’s easier to keep track of the issues there. Also please make sure that you check the FAQ first. You can find the forum here.
