One-Page Checkout [Support Thread]

[linuxguy2]

The single change in the as-distributed /includes/classes/order.php is already included in zc156+. Just restore that file to its Zen Cart "base" version.


Is "Money Order" one of the payment methods allowed for guest-checkout?

Guest checkout is disabled.
On the "Confirm Order" page "Check/Money Order" and Free Order are listed under the Payment section. Those are the default in the admin modules payment selection page.
I am not using any CC processing selections.

On the Order Total Modules page everything is enabled except the ot_cod_fee

Let me add that on my production build I will be using the PO_Number plugin.
I will never be using the guest-checkout function.
NOTE: I get these same errors on my production build where I am using the PO_Number mod and it's my only selection.
