Thank you very much for trying to help. I hope I can answer your questions. I have close to no experience with servers - except just uploading html files etc to web hosts that just work 
- and I didn't make the settings for this domain at the web hotel - but I do have access to changing them.
Is localhost a local server? No I didn't try that.
I made a new GS test site from a new download of GS just to test - but with the same result.
The GS test site is at capelle.dk/test3
I think I am actually reaching the correct folders - cause when I call (in a browser) a folder or a file (at capelle.dk) that doesn't exist, I get a different error message. It seems like GS (combined with the server php-settings or something?) is blocking access to everything under the GS root. The main site capelle.dk (with html files, images etc) works as normal including all subfolders except the GS folder.
On the server the path to capelle.dk is /www/capelle.dk
