Double Processing Issue When Using Send_Order_Notification Function

Store Builder Questions

When I use “send_order_notification” function in fn.cart.php it process twice.



I use like this.

<br />
function fn_my_addon_send_order_notification($order_info, $edp_data, $force_notification, $notified, $send_order_notification)<br />
{<br />
fn_print_r("TEST");<br />
}<br />

```<br />
<br />
It process two times and print TEST twice. Where do I make mistake?
