I have been using Klarna Invoice and Klarna Account OC core since I upgraded to 1.5.6.
In september I had Bivo in Sweden install the Klarna Checkout solution. Something went wrong, and I had to remove it.
Now I can not get the original Klarna payment methods to work. I have overwritten all the files with the OC 1.5.6 files, but still no luck.
Please can someone help me look at this
