I require a fix for a small but annoying issue for a Prestashop 126.96.36.199 site. Because of an out of date currency rate the exchange rate shown by Paypal doesn not match the site. When paypal returns the order to Prestashop the order is flagged as having a payment error. This only happens where the currency is different than the site default. I require a sustainable solution implement quickly.
Many thanks for your interest in bidding.
