The off-canvas cart shows "The payment method PayPal is blocked for your current shopping cart." / "Die Zahlungsart PayPal ist für Ihren aktuellen Warenkorb gesperrt."
How do I remove this warning?
If the cart is 0€ I don't want to show PayPal at all.
I found a solution in the forum using the "Always valid (default)" rule but this does not work for me.
This warning is shown if the customer has selected PayPal as payment method in this account see /account/payment. In my very special case I solved it by resetting all customer payments to another payment:
UPDATE customer SET default_payment_method_id = X'C6139B2C8E8541028EEFCC2D60D80820'
