Orders Malfunction - Not Sending Orders to Admin

I've set up a new site at https://www.superfancy.co.uk

This is in it's testing stages at the moment, but I've hit a bit of a stumbling block in the order process. The orders are going through and e-mails are being sent etc., however, new orders are not appearing in /admin/orders

What could be causing the breakdown in communication that's stopping the new orders being logged to admin area?

That's based on the payment module you're using, which you haven't mentioned.

Also, you said you're setting up a new site ... but you're using an older version of Zen Cart. You would be wise to use the newer version to benefit from the bugfixes and save yourself having to do an upgrade later when it's live.

None of the payment options work.... PayPal, Nochex, Google, COD, none of them put the order into the admin area.

I've narrowed it down to a database problem. Restoring an older database corrects the issue, but puts me back a very long way in developing the site.

I can't figure out what part of the database is causing this.
