@pittigeteksten;
Your problem appears to be cause of the assignment of the template to a menu. In order for Home page and other page to look differently, you apply for each menu a different template! You can not apply only ONE template for all the menus.
So for hope page this is what you apply http://prntscr.com/3kkjro
For the the rest of the pages i applied the template you have created or/and renmaned http://prntscr.com/3kkk0l
The problem was no matter what you click there was no content displayed because in your template this was the layout type you choose – http://prntscr.com/3kkk73
As you will see bellow it does not display a content of a article; in order for a content to be displayed you need to choose one of these – http://prntscr.com/3kkkd7
So every menu or menu item if you want it be lay outed in a special way make sure it is assigned to the correct template layout style;
