Testing with the PayPal sandbox

Troubleshooting

PayPal has introduced a new Merchant Tools feature called “Auto Return”. If you select this option in your account, PayPal has you add in the URL you would like your customers to return to on your website. What actually happens is that you are directed to the Thank You page that gives an error message “Sorry there has been an error”. You will also not receive order confirmation.

The Auto Return feature can be used though in conjunction with PDT - Payment Data Transfer (Version 5.1.0 minimum required). You will need to add your PDT key to the admin payment provider PayPal page. Implementing this will allow customers to return to your store without clicking on the "Return to Merchant" link from PayPal. Godaddy hosting customers only will require this addition to vsadmin/includes.php

If in your admin orders page your PayPal payments are showing with a status of "Pending: unilateral" then you wil need a verified Premier or Business account for PayPal IPN. The message of Pending: unilateral comes up when the account isn't verified. The solution is to check again that you have completed all the verification steps for your account and that it is a Premier or Business account.
