Mines not working, nothing on left side of screen, no friends list , not who's on or playing, Oh well, saw this going downhill over 3 years ago.
Is flash enabled? It is required for those to show.
Sometimes it takes a reboot to get things cleared out to work again.
I use Chrome and I have always set my browser to ask before running flash on any site, since it could cause a problem in the wrong hands. I notice that Chrome keeps warning me every time I start it about Flash going away - I'm trying to get rid of the warning without losing flash!
Good luck, Rich.
