Thanks VIPStephan for your reply!
I have fixed it, but it does not help? I have checked everything, all the files are uploaded correctly... The file switcher2_bd02bfd0.php.css is there...
Excuse me for my broken english, I'm dutch
I have been checking that file... I've downloaded firebug and when I select this switcher2_bd02bfd0.php.css file, it says that there are no lines and I have to click it to edit/add lines. So I have copied and pasted the code from dreamweaver and voilà, it shows the website correctly.
I have uploaded it many times, but it wont fix it?
I found out that is has something to do with Apache, because it can't properly read .php.css or something.
I've read that I need to add "AddType text/css .css" to the .htaccess to get it fixed. So far no luck.
