I am trying to install Klarna payment module.
After uploading the files via FTP and logging in to admin in oscommerce I can see the klarna payment module when pressing "install module" .. i highlight the "klarna invoice" and press install.
I then get back to main screen I it looks like klarna is installed but as soon as I click on something it disapere..
I am following klarnas own instucions step by step and cant figure out what I am doing wrong.. any clues?
I have change the currency to SEK(swedish krona) as klarna as and so on..
