Server
There were performance issues with the server. Updating the view counters in each thread occupied more database time than any other thing the VBulletin software did.
The view count was disabled in order to help prevent the board software from crashing like its been in the past month. This is a temporary measure until a permanent solution is found.
This just shows you how much TDR has grown in the last year. Site count is an order of magnitude higher than it was 12 months ago.
