http://www.netzgeier.de/ (WordPress 1.5) shows up just fine in Safari/Mac (aka KHTML) but when viewing it with any Firefox/Mozilla/Camino variant on the Mac, the page doesn't work - while all articles and links are actually display, all the nice formatting has gone. It basically looks as if the css is completely ignored. This happens regardless of the theme chosen.
Opera (8.0 beta on Mac) works fine. However, I can reproduce pretty much the same effect when toggling between "author mode" and "user mode" in the Opera toolbar.
Any ideas anybody?
Thanks in advance,
