I have a site that launched with a SERIOUS ERROR!
OsCommerce 2.2 with Cybersource Gateway -- In TEST mode, the charge info goes our to Cybersource, user returns to site where they get confirmation, receive confirmation email and order is added to Orders in Admin.
Switched to LIVE mode -- user leaves site to go to gateway, then gets the screen in the attached screenshot, never returning to site, never receiving confirmation email, never having order added to Orders in Admin.
NEED THIS FIXED RIGHT AWAY!!!
