Update - The homepage (a static page) linking seems to works fine now, its only the pages that doesn't show its content. Can't figure it out.

But everything seems to work when I disable the nice permlinks and use the default form (http://artinstockholm.com/?p=123). Is it any way I could get (http://artinstockholm.com/exempel-inlagg/) to work?

Any ideas.
