PAS not working?

I have installed PAS on my domains www.megasjov.dk and www.gevinstspil however it doesnt seem to work. I get an error 500 on the domain. I tried uploading a regular index.html file to test the dns and that is working fine, so there must be something else wrong?! Admin-part is working fine..

check your site's error log, maybe the answer is there... usually the reason of error 500 is wrong access
attributes for a file or folder.

For more help I'll need ftp access to your site.

You are right :-) The folder "templates" and all subfolders and files needed 777-rights in order to work..Now everything seems ok.
