WP-admin errors, editor not working etc

Hello,

The editor in wordpress is not working, I installed a 2.8.6 .. thought that an upgrade to 2.9 would fix my problem, but nothing. So then I did a clean install of 2.8.6 (with files from a working installation) , but still no luck.

Basicly the font in my editor is white, and I have no functions whatsoever, I’ve tried some steps in other topics but no luck.

My FF error console shows these errors :
