Current Posting Problem
All right, I'm not sure what to do with this so bare with me. Some users have received errors while posting, which seems to be causing double posts/missing posts if I understand correctly (probably not). I've got one of them as an example.
If you get this error all I can suggest is report it here, open the topic you're posting in into a new window (if you can) and check if the post was submitted. If it wasn't repost it.
I'll have a look to see what the problem is but like fred says it's probably got something to do with the database when it was "fixed"/altered before the site/forum move. Unfortunately with all the posts that have been done since then, (it was only a few weeks ago as well) I can't just reupload the backup or we lose all the posts. It's a last resort though, but I doubt it'll have to be done.
