The box on the left (Named "Medlemskap" on top) and the box on the right (Named "Reklam" on top) is just php includes put in the header and footer files.
First I didn´t know what empty boxes you where talking about. Then I logged out and refreshed the page. And there the sidebar was! Not good looking (seems to be some language stuff missing: how can that be?), but it is there!
Is sidebar really supposed to replace the entire IIP page like this? I guess that will be prevented by adding $config['iip_call'] = 1; to my IIP index page?
But... as soon as I log in it disapears! Strange!
