Okay, I think I've found the fix. There was a database issue that was causing the problem. Fingers are crossed!
There is an
announcement on all the forums that detail the new posts feature. Basically, you'll want to go to Quick Links > Mark All Forums As Read. This will "kick off" the new posts feature.
Just noticed a layout issue when visiting the announcment.

One thing fixed, another thing breaks.
Feedback, as always, is greatly appreciated. I'm hoping this resolves the issue.
