Your saved payment method (Klarna - Invoice or PayPal) has unfortunately expired.
As the payment method cannot be saved permanently for security reasons, please delete it once and add it again as follows:
In your customer account:
- Under the payment methods option, delete the payment method with the X on the right
In the cart:
- Click on "Change" directly next to the payment method
- Then select the desired payment method in the new window
- Confirm the new payment method with "Select this payment method"
It may be necessary to verify again via Klarna or PayPal and you can now pay as usual via Klarna invoice or PayPal, or you can use one of the other payment methods at any time.
