First, did you install the osC 2.3.4.1BS "Frozen" (or "Edge", if adventurous) or the official 2.3.4.1 (from this site)? Frozen is the correct one to use (see the link in my signature), as the official version is obsolete and won't run correctly on current PHP levels. Second, is the Danish language package marked as being for the official version or the Bootstrap (Frozen or Edge) version? If you have a mixture of versions, it probably won't work. If you have Frozen and the only Danish package is for the official release, you'll have to do some work to compare English versions and update the Danish accordingly.
