We've got a user that is having problems with the way the ZImbra Web Client is displaying. He basically gets a black and white screen, and none of the icons show up. We've tried all the basics; log off and back in, clear cache, change theme, etc., but nothing has helped. Thought it might be something broken in IE, so we downloaded Firefox and he gets the same thing. Switching to the basic client doesn't really help. He can see some icons, but still all black and white.
I've only seen something similar one time on another user, but she had been playing around with changing themes, and a simple reload fixed the problem.
Anyone have any ideas on what may be causing this?
