One-Page Checkout [Support Thread]

[Jeff_Mash]

Cindy - Can you tell me how to fix this specific behavior?

I have a custom payment option called (Pay Later). It's basically the check/money order module, just renamed to say "PAY LATER".

After the checkout page loads, if I just select the PAY LATER option (and nothing else, leaving everything else default), then when I hit the Submit Order button, the page refreshes and keeps me on the checkout page with an error: "Your order's details have changed. Please review the current values and re-submit."

If I immediately hit the Submit Order button again, it submits and works just fine.

How can I configure the module so that the order submits on the first time? Do I need to have the page refresh after the Pay Later option is selected, much like it refreshes when the shipping options change?

EDIT:

I am using OPC version 2.4.5, and my store is running 1.5.7
