Its says bad request and the url to it is at http://www.owshit.se/gallery

The error is probly because of the .htaccess file and my is this:

RewriteEngine on

RewriteCond %{REQUEST_URI} !.*__phpAutoGallery/wrapper\.php.*
RewriteRule .* gallery/__phpAutoGallery/wrapper.php [NE,QSA,L]
#RewriteBase gallery/

And I have lookt in the forum for 'my case of error' but not found it.
Thanks
