The cart has been working fine using Paypal in addition to our gateway but in the last few weeks we are now getting an error.
- User selects they want to pay with paypal
- On the confirmation page where you check to agree to the terms click "submit order"
- Note that "submit order" is suppose to take you to paypal to complete the payment. It does not, instead it refreshes screen and gives back:
Error processing payment. Please try again. PAYPALSTD
What is causing this and how do we fix this?
