Dear!
First of all: i have read the post about this problem.
BUT... i have this problem for about 2 weeks and it drives me crazy. I can't run my shop....
It is a 'famous' error but i can't solve this problem. Who can help me with specific reactions?
I installed Paypal express at my online shop. Once someone made a payment they got the error:
PayPal Express Checkout Error (10413)
I changed much things about the taxes etc.
Is there is something i must do to solve this problem?
