Just tried out the PayPal Restful module, and on the checkout, when you go to make the payment, the following error message is generated:

The required notifications in the order_total.php class were not applied; the payment module cannot place orders. The payment module has been automatically disabled.

The plugin module then turns itself off, and enable this plugin module status changes from true to false.

have double checked all the settings within the module, and all appear ok.

Not sure if anyone else has experienced this, and if so, if they managed to find what was causing the issue?

Kind Regards,

Andy
