As you guys know, A4 went down for a couple of hours last week.
The vBulletin software got upgraded to address some security issues, and it was actually upgraded several versions up from the previous one that was installed.
During the process, it caused a couple of past vBulletin plugins and add-ons to be either obsolete or broken. During the wake of the situation, Knuckles10 and I decided to either turn off some of the plugins or remove them completely.
I've gone ahead and fixed a bunch of PM'd bugs like the Avatar.
The Sidebar is a WIP and should be back up and running soon.
If there are any bugs and problems you guys are encountering, feel free to PM me or continue to post them up in the Suggestions and Support Forum. I do look at them, I may not answer most of the time, but I do look at them. I do appreciate you guys for understanding as software is finicky and does take a bit to maintain.
