I am in the final stages of transfering my 1.3.7 cart over to 1.3.8a and when I did a test purchase, I get the following error after confirming the order.
I can not find anything about this error.[scr]http://www.mommyandbabyessentials.com/test/includes/templates/template_default/images/icons/error.gif[/scr] 10002 Security error - Security header is not valid
I am using website payment pro, express checkout check/money order and local pick up.
Any ideas what the problem is?
