One-Page Checkout [Support Thread]

[OJ_SIMON]

Customers have been experiencing issues while checking out.

After clicking "confirm order", the screen refresh with a red highlighted message: " Your order has changed. Please check value....and resubmit"

I tried a test order and i am getting the same message. If i try several times, the order eventually goes thru.

Any ideas on how to fix it please? Thank you

It has been happening since a couple month i believe. A customer mentioned a while back but never paid much attention to it thinking it could be internet connectivity, wifi, or operator error....

Thank you Simon for mentioning the update. I didn't know there was one honestly. I will give it a try and see if it fixes it. " finger crossed"

again I shouldnt play with things, added this to advanced shipper to not show when free shipping is enabled but didn't add a method

	if (IS_ADMIN_FLAG !== true && $this->enabled == true && isset($GLOBALS['freeoptions'])  &&  $GLOBALS['freeoptions']->enabled && $method == '') {
       $this->enabled = false;
       return false;
      }

zc 1.58a. php 8.1. opc 2.5.2.

I received the following warning.

Request URI: /ajax.php?act=ajaxOnePageCheckout&method=updateShippingSelection, IP address: xxxx, Language id 1
#0 /includes/classes/ajax/zcAjaxOnePageCheckout.php(115): zen_debug_error_handler()

#2 /ajax.php(85): zcAjaxOnePageCheckout->updateShippingSelection()
--> PHP Warning: Undefined array key "opc_saved_order_total" in /includes/classes/ajax/zcAjaxOnePageCheckout.php on line 115.

Line 115 is the following section:

    protected function formatOrderTotal()
    {
        return $_SESSION['opc_saved_order_total'];//line 115
    }

Does the following change work? $_SESSION['opc_saved_order_total'] should not be zero or null?

return $_SESSION['opc_saved_order_total'] ?? '';

Hmm, that shouldn't happen. Does the associated site, by any chance, have something like the "Remember Me" plugin installed?

Hi @lat9,

No plug-in, but I added a php file to extend the session/shopping cart expiry time. Not sure if it is related.

<?php define('SESSION_TIMEOUT_CATALOG', 7200);

This file is under /includes/extra_configures/my_ultra_long_session_timeout.php file
