Anybody having rendering problems may want to update their HTML5 shiv and use Peter’s code that he mentioned the script can be found here. I was having problems with IE8 (no problem with safari, firefox) Updating the html5.js and adding the code that he mentions fixed the problem. Thanks Peter! Hope this helps somebody.
One addition, this can also happen if you have set a webdav realm on your site with Mac OS X server. To get around it, I made a new realm called uploads so that www could upload to the uploads folder.
I did the same thing as appanews. You have to make sure you have actually created the uploads folder and chmoded it to 777
In UNIX or Mac OS X this is done with the following command (make sure you are in the wp-content folder already…
mkdir uploads
chmod 777 uploads
Wierd….
