Strange Display Issue with Zimbra Web Client

[soxfan]

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?

Thanks,
John

Can you post a screenshot?

Here's the screenshot. I rather hastily blocked out some of the info to protect the names of the innocent, so to speak I think there's enough here to get the idea. The more I've investigated, the more it appears that the user has in some way messed up their display settings, rather than it being a ZImbra issue. However, I'm having problems reseting things, so if anyone has any ideas that they could pass along it would be greatly appreciated.

One possibility is that their browser isn't handling CSS at all. We use CSS rules for a ton of stuff, including colors and images which are lacking (except the Zimbra logo). Weird that it's happening in both IE and FF.

Things to try:
- View their account on another machine
- Go to Yahoo Mail or GMail on their machine, see if they're messed up
- Reinstall IE and/or FF

Also, just to touch a little on what conrad's saying, what about Antivirus programs? Sometimes they can interfere.

Thanks for the suggestions. When logging in as the Administrator on this same machine the Zimbra web client looked fine, so this user obviously did something to his settings to cause the problem. Other web pages didn't look right either, although perhaps not as bad as the ZWC. After playing around a bit trying to get his settings (IE, display, etc.) back to default and not seeing any improvement we ended up just giving him a new AD login. Once he logged in under the new account everything was fine.

Well, I thought this was a one shot deal, and that this user had simply manged to change a setting that caused the problem. However, Friday we ran into two more users that had the exact same problem, and just today we added one more to the list.

Pretty much all our users are currently using IE6. On these problem users we tried upgrading to IE7, but that did not help. We also tried Firefox, and that looked even worse. I have considered the suggestion about the anti-virus program interfering, but all our users have the same A/V program, Symantec Corporate Edition 9.0. If it was Symantec I would think the problem would be more widespread.

I don't think this is strictly a Zimbra problem; just that the Web Client looks a lot worse than other sites, probably because of all the CSS stuff, as mentioned in one of the responses. However, if anyone has any further suggestions it would be greatly appreciated.

It looks to me like a server or network issue.
Do you have any filtration device like websense on your network?
What about a content Engine?

We found the solution to the problem and I figured I would post in case anyone else runs into the same issue.

Click on Start --> Control Panel --> Accessibility --> Display --> uncheck "Use High Contrast"; restart IE.

I found this solution on the mozillaZine web-site. For reference, here is the link:
