I'll add the suggested file in case this happens again.
if you are not using OPC, and you have had plenty of successful transactions, pretty sure the issue is on the customer side. or potentially loading of multiple versions of jquery on the site. which i am not seeing on your site.

i have changed the logging of that message, as there is no need for the rest of the post vars. you can upload this file (in its respective place) as well:

i should be submitting an updated version soon. but the changes are really for error logging and troubleshooting as the core part of processing cc transactions has not changed.

best.
