I have an eCommerce website built using Couch CMS - [url removed, login to view]
The shopping cart is built using jCart and PayPal. It was working fine, however over the past few month it has not been functioning correctly. You can add to the cart and view the cart, but for some reason when you checkout, an error via PayPal comes up on screen. Also it appears to be working on some computers /devices, but not on others. Please see attached some screen grabs of the errors.
I need a confident and experienced freelancer who can quickly fix the errors that are occurring.
