Non-Working Payement Gateways under 503

Imported From: http://groups.google.com/group/in-portal-bugs/browse_thread/thread/31a652fcbe00deb6#

Hello guys,

I've updated to 503 a 439 version, and payements done via payement gateway
are never completed: checkout success is displayed, but order stay as
incomplete, and shop cart isn't emptied.

No error in error log file, nothing special in access log. I haven't been
able to guess the problem from debug mode. Have you tested incommerce
gateway under 503?

I can provide you full test info in private message (website in production).

Thanks
Phil.
