VMPAYMENT_PAYPAL_ERROR_POSTING_IPN

[joaobraga]

I have developed a Ecommerce website (virtuemart) The website checks out with PayPal. I am having an issue with IPN.

The situation:

Business PayPal Account checks out on the website goes through to PayPal. PayPal authorises transaction and the money is taken with no problem at all. No error comes back. The order status goes back into the website as confirmed.

Standard PayPal user checks out on the website goes through PayPal authorises the transaction and the money is taken. However I get an error for IP (see below)

ERROR validateIpnContent: VMPAYMENT_PAYPAL_ERROR_POSTING_IPN

The status of the order in the website is Pending.

I get this email: An error with your payment paypal on your store XXX" referencing an error log file, paypal.1.log.php ...

The error log file is this:

#
#<?php die("Forbidden."); ?>
