Checkout Success page coming up with error message

[Salina13]

There isn't anything recent for that site. It doesn't seem like its making an active error, its just not loading pages or something strange.

Try navigating around your site ... and when you hit an error ... go look a your error logs and see if anything shows ...

I never did figure out why I am getting this error message in the store. It doesn't create an error in my error log in cpanel so its not something that is going on with the server, its directly related to the zencart files.
The funny thing is that it still sends out the order confirmation emails and shows the order in zencart. So everything is going through properly, it just won't come up with the confirmation page at the end.
Anyone have any ideas?
