Okay, the real JBW thread was heavily affected by the server update. Frank has told me that it will be fixed by the end of the week so, use this until Friday I guess. Here's the message from him:
Update: Server and vBulletin should be updated by the end of the week. There are certain forum threads being effected. I will have ahmed look into this as soon as he finished updating. We will also have to rebuild the database, which might fix it... either way, we have a back up for the data and will not be lost.
