I am experiencing the error below on a live site when customers choose paypal as form of payment.
I am using Nop 1.6
It was working fine for the last year the error just happened.
All settings (API etc) were working fine and no changes have been made to NOP cart.
Can anyone help me with figuring out what the problem is and how to fix it?
