I've got a dev version of OpenCart setup in anticipation of setting the website live some time in the next couple of weeks. I am getting an error when editing orders however:
This shows up when I click 'Edit' on an order in the admin, and then click the 'Continue' button.SyntaxError: Unexpected token <
<b>Notice</b>: Undefined variable: json in <b>/home/linweb38/u/modusdemo.co.uk/user/htdocs/admin/controller/sale/order.php</b> on line <b>2490</b>
Can anyone help?
