Unable to get checkout to work
I have set up my new site with PayPal API credentials and I have not been able to check out. I really have no idea what else to look at to make this work.
It lets me compleatly check out with my paypal account or a credit card then returns me to the site with a message of
" Transaction Not Completed
Your transaction could not be completed. Either your credit card information or billing address has problems and cannot be processed
Please return to checkout and try again. "
