Thread:Project:Support desk/Display problems on chrome and firefox!/reply

What you see in Firefox/Chrome seems to be like your stylesheets do no longer get loaded. So I would check the source code in the browser and see what happens, when you try to open one of the stylesheets.

As you describe the problem (first it worked in both browsers, then still in one and now in none), this might well be a caching issue. My guess is: Clear the cache in IE and it will be broken there as well.
