I installed paypal express and got this error -->
I installed paypal ipn. Now, my store redirectet to paypal, but I can see the total price is 0.
An error occurred when we tried to
contact the payment processor. Please try again,
select an alternate payment method, or contact
the store owner for assistance. (10401) 10401
Transaction refused because of an invalid argument.
See additional error messages for details.
- Order total is invalid.
I think I got the paypal express error because the price is 0. I don't know.
I hope someone have some tip for me! :)
