We are getting the following error on many of our orders (not all):
PayPal Validation Error: Payment amounts do not match initial order (gross **.**). Order status changed from pending to on-hold.
The issue is being caused by the shipping amount.
Shipping is set at a fixed rate, it is passed to PayPal correctly but the order in WP says something like:
Subtotal £9.25
Shipping £4.00
Total £9.25
Any ideas?
Thanks.
