Hello,
The outstanding issue was fixed in version 1.3.3 or below. If you haven’t updated your template then this would not have been fixed. Check your template versions. You will see that we call $order->get_order_number(). Which is how all order numbers should be displayed. We are using the built in internal woocommerce functions to display and retrieve order numbers. This is also the suggested way to be compatible with the plugin mentioned above, so according to them, we are already compatible.
Also the error you’re getting is a javascript error and has nothing to do with the underlying order id. That error is saying that some function doesn’t exist called ‘addthis’ which we don’t define. So something is calling that when it shouldn’t be.
cheers,
Jamie.
