One-Page Checkout [Support Thread]

[lat9]

I'm in a loop with "Your order's details have changed. Please review the current values and re-submit." on every Confirm Order.
I did copy JS files from includes/modules/pages/checkout_payment to includes/modules/pages/checkout_one. Should I generate a log file or do something else?

What payment-method(s), shipping-method(s) and order-totals are in use? Ditto for the currently-active template and the OPC version.

Payment methods: authorize (AIM), check/money order, PayPal Express.
Shipping methods: USPS
Order Totals: Coupons, Free Gift Chooser, Group Pricing, GV, Low Order Fee, Shipping, Subtotal, Tax, Total.

Template: yourstore (from Perfectus).
OPC is latest and greatest. 2.2.2

Most likely that template (which is identified in the readme as not compatible). If you generate an OPC log of the transaction and send it to me via direct email, I'll look to confirm my suspicion.

Rats, I completely missed that.
I would be willing to overwrite some template files from yourstore if I could get this to work - please let me know if that's an option.

Got the log, thanks @swguy. There are two discrepancies between the before payment and totals' processing and the after processing which are causing that redirect back

1. The payment method (moneyorder) isn't being recorded into the session prior to the "Confirm" button click.
2. OPC looks for the order's current total via jQuery/HTML selectors; on entry to the confirmation step, it's found 'Total:' but the total value after processing is (more correctly) $23.30.

Each of those discrepancies is sufficient to cause the redirect. The latter is what I've seen before with the yourstore (and other Perfectus) templates; I'm puzzled by the lack of recording of the payment method.

Issue #2 turned out to be what broke OPC. If you want to use yourstore + OPC be prepared for mucho CSS hacking, but beyond that, the key fix I added is in includes/classes/order_total.php.

I recently loaded this plugin to a brand new site that I am working on.
I am using the latest version of zen cart 156c
I am getting the following error when opening my admin panel

The One-Page Checkout plugin has been disabled. The file "/home/xxxxxx/public_html/xxxx/includes/templates/westminster_new/jscript/jscript_framework.php" is required for the plugin's proper operation.

I admit I am not great at adding plugins so I have no idea what this error means. I did find in the plugin that there in the docs folder there seems to be some jscript files.
Do I need to load these and if so where?

Thanks in advance for any help.

You'll need to copy the file /includes/templates/responsive_classic/jscript/jscript_framework.php to /includes/templates/westminster_new/jscript/jscript_framework.php.

Very much appreciated.
With my knowledge in this stuff I know I would have not figured that one out. Thanks for the education.

OPC 2.2.2, Zen Cart 1.5.6c.
Entering a coupon code on the checkout_one screen causes the success message to be shown twice. See image.
Seems to happen on all templates (here shown on responsive_classic).
