Sitemap File Not Found

Hi. I'm having trouble with my sitemap.

I went to the sitemap at http://mediesjef.no/sitemap.xml
but I got this message:The sitemap file was not found.

The plugin says that the Path to the XML Sitemap is:
/home/mediesj1/public_html/wp-content/mediesjef/opplastninger/sitemap.xml
but theres no such directory in my wp-content folder.

What am I missing?
