Brief
We have updated the script "worldpay_confirm.php".
 
Description
When you activate callback parameter in Worldpay settings and then make a transaction in ViArt you can see such error:
Fatal error: Call to undefined function prepare_js_value() in
.../includes/order_items.php on line 1423
 
Solution
Download the updated version of the file:

Further, extract the "worldpay_confirm.php" into the 'payments' folder of your shop replacing an existing file. Please do not forget to make a backup copy of the current file in case something goes wrong.
