Sorry for the confusing topic line; I couldn't think of a better way to word it.
Anyway, my problem is that I'm missing all account-related things on the forum. I'm missing my profile picture in the top left, I'm missing my personalized welcome, and I'm missing my "unread posts since last visit" and "new posts since last visit" links.
I know I'm logged in because
A) I logged out and back in again.
B) There are still "new" tags against things that I haven't read.
C) The link to "unread replies" that I have bookmarked still works as intended.
Mobile devices and other computers have the same problem.
The problem showed up about a week ago, I've been looking through options and account settings off and on, and have officially decided that I'm stumped.
Anyone know how to fix my little problem?
