I thought I had this error fixed ages ago but found out I did not.
EE 2.5.2 CT 2.2.2
When checking out with paypal express I get the error
The totals of the cart item amounts do not match order amounts. 10413
This error ONLY occurs when I have a shipping charge. Currently shipping is defined per product. If Shipping is not required I do not get this error.
SOLVED an EE and CT upgrade seemed to fix this issue
