never seen this problem before on any other website but when we try to checkout via paypal express when trying to use a discount code we get an error
Transaction refused because of an invalid argument. See additional error messages for details.(
I enabled paypal logging but the long message just says:
The totals of the cart item amounts do not match order amounts.
I have checked the magento configuration but I can't see anywhere I can remove this check like I can with other payment providers, any advice?
Theres an option to transfer cart line items over to paypal but that's set to "no"
