I am playing about with some ideas offline before implementing them on the site.
I have created a product that requires no delivery and is not a physical product.

I add the product to a page using a product block and the 'select product' option. No callouts or overlays. Just a price, description and add to cart.

I was logged in as admin while doing all of the above.
Allocating the product to a page and selecting 'Inherit from current page' makes no difference. Same errors.
This doesn't appear to happen on an existing site/installation on my dev system. Only on a newly installed site.
Never mind. Updating the fresh install to the latest eCommerce solved the problem.
But why did the existing eCommerce installation work OK on the same previous version? But not this installation?

I'm not sure why it wasn't working, but your original error makes it sound like `$orderProductID` is null where it shouldn't be. I'm glad to hear updating fixed the issue :)
I suspect that data somewhere was lax about differentiating between null, empty string and zero with SQL parameters. Perhaps relating to the first ever cart.
