CubeCart v4 Critical PayPal IPN Update

Recommended Posts

Over the past couple of days PayPal have been performing maintenance on their servers and they have updated their Instant Payment Notifications (IPN) software on their servers to version 2.6. It has come to our attention that since this release the CubeCart v4 code has stopped working if your store uses cURL rather than fsock to communicate with their servers.

Before this file update CubeCart specified the server path in a POST header. Since the IPN update the PayPal servers no longer accept this as a method returning a '301 permanently moved' error message.

We have patched the PayPal module. To update your store please upload the attached call.inc.php file over your existing one.


CubeCart v3 is not affected by this issue.

Please note that a new release of CubeCart v4 is due any minute. This will contain this patch, security hardening and some bug fixes. More information concerning this will follow soon.
