When using paypal restful live. I get the following error log when the order is confirmed.

I know this is connected to the old paypal method which I have set to retired. Have I missed somthing at the paypal end?

I tried disabling IPNs from the PayPal account (removed the soap method from PayPal), it made no difference. I managed to stop the error by setting PayPal Express checkout to 'False' rather than 'Retired'. I now don't know if this is a paypal issue or a zen cart issue?

I am using zen cart 2.0.1 php 8.3
