One-Page Checkout [Support Thread]

I'll put my money on Advanced Shipper. Try changing the store's shipping-method to flat-rate to make sure that there aren't additional template-based issues.

Disabling adv shipper made no difference and the console isn't reporting any additional errors. Standard Zen Cart checkout is working fine in either case. I am happy to share login creds and site in PM if you want to look.

Sure, send them on. If you'll install "Display Logs" so that I can 'see' what's going on, I'll only need admin-login credentials.

The checkout-loop that @mprough reported in post #1693 above was due to the changes made in #1692, which applied the id="OPC" to all order-totals, causing OPC's jQuery to pick up the value of the order's sub-total instead of the total.

That discrepancy was the cause of the checkout-loop. Here's the correction for the Bootstrap template's /templates/tpl_modules_order_total.php:

<?php

 ?>
<?php 
/**
 * Displays order-totals modules' output
 */
  for ($i=0; $i<$size; $i++) { ?>
<?php
//-20200718-lat9-Only apply the id="OPC" for the order's total
$value_parameter =  ($GLOBALS[$class]->code == 'ot_total') ? ' id="OPC"' : '';
?>

<tr id="<?php echo str_replace('_', '', $GLOBALS[$class]->code); ?>">
<td colspan="2" class="text-right">
<?php echo $GLOBALS[$class]->output[$i]['title']; ?>
</td>
<td class="text-left"<?php echo $value_parameter; ?>>
<?php echo $GLOBALS[$class]->output[$i]['text']; ?>
</td> 
    </tr>
<?php } ?>

If you're using that, you'll also need to change the OPC's order-total selector's configuration as identified in post #1692 above!
