I’m running into a problem while I am integrating PayPal into my WordPress account. I’ve created sandbox account to try and run the payment. However, whenever I tried to ordered the item, it gives me this error:
Fatal error: Payment error code: #00003 in /home/www/d-xchange.com/wp-content/themes/classiads-2-2/paypal/form-handler.php on line 133
Does anyone has any experience in this before? As I’m not too sure whether the problem occurs in the integration or my sandbox account.
Hope to hear from you all soon.
