I'd like to give a little bit of background about what it going at mp3car and the status of the forum upgrades. We are currently in the process of re-designing the entire mp3car.com website and a large part of this will be developing a unique visual theme that we'll apply to the home page, the forums, the on-line store, as well as new features such as user image galleries.
Previously, mp3car.com was running version 3.0.8 of vBulletin, and I had installed the current version of vBulletin (3.5.0) on the development machine in the office. I had wanted to integrate all of the visual changes into 3.5.0 and then roll things out once, but the the vBulletin software upgrade got pushed ahead and didn't get the level of testing it fully deserved. Unfortunately, I was the only one who did any testing, and I missed some of the visual items such as the Avatars.
There were a number of major functional changes between the 3.0.x series and the 3.5.x series of vBulletin and one of these was the templating system which drives the look of the forums. The old templates are only partially compatible with the new software. So far, we've hacked the old templates to work (though not completely) but the real solution is to apply the updated templates designed for 3.5.x.
I'm currently in the process of putting together upgraded templates on our development machine, and I'll have the moderators and long-time forum members proof this to make sure everything is OK before we roll these changes into the live site.
Please rest assured that all of the old functionality will be restored during the coming week. In the meantime, please bare with us while we take care of this.
