Can't see order list in Admin

[dharrison]

Hi all

I have just upgraded our website on XAMPP from 1.5.4 to 1.5.6C and I have a pretty major issue:

in the back end, I go to Customers > Orders and I am greeted with a blank screen

The error log reads

[29-Jan-2020 16:13:42 Europe/Berlin] PHP Fatal error:  Uncaught Error: Call to a member function get_content_type() on null in \mypath\includes\classes\order.php:281
Stack trace:

#1 \mypath\myadmin\orders.php(90): order->__construct(false)
#2 {main}
  thrown in \mypath\includes\classes\order.php on line 281

\mypath\includes\classes\order.php:281 read

   $this->content_type = $_SESSION['cart']->get_content_type();

\includes\classes\order.php(50) reads (in red)

 $this->notify('NOTIFY_ORDER_INSTANTIATE', array(), $order_id);
    if (zen_not_null($order_id)) {
      $this->query($order_id);
    } else {
      $this->cart();
    }
  }

And \mypath\myadmin\ line 90 reads in red

 $jsweb_sage_pay_admin_module = null;
  
  if (isset($oID) && (!isset($order) || !isset($order->info['payment_module_code']))) {
    $order = new order($oID);
  }

I have asked Sagepay as well, I was just wondering if it was anyhting obvious?

I welcome any help.
