I have in my OpenCart store the transparent checkout payment module I noticed that on rare occasions, a client could not make the payment by credit card. Today a customer came to the store and it happened again just when I applied any discount (in the value of the sale and not in the product) it throws the following error
installment value invalid value: 247.82
After some research I have seen that it is probably because the error of plot value does not match the value of the products.
Is there any way to tell the payer how much discount was applied or how to resolve this error?
