Magento - Fix Warning after compiling

Easy fix

As I can see it's a mistype in the file app/code/community/Klarna/KlarnaPaymentModule/etc/config.xml find this line: Klarna_KlarnaPaymentModule_Model_Order_status it should be: Klarna_KlarnaPaymentModule_Model_Order_Status Then clear configuration cache and run compilation. Enjoy:)
