Q1 I received the following error: Something went wrong…” while trying to set up Smart Checkout Options. How do I fix this?

Solution: The smart checkout option requires correct API permissions for it to work. If this is not setup correctly you will run into all sorts of issues, this might mean that the current PayPal Merchant account has some issues. The following test might help you work out if it is a PayPal account issue. Turn off the smart checkout option (in the settings menu of the plugin). Keep only the standard checkout. Does that standard PayPal checkout option work with that account? Check the following link forum post to learn more.


That is how simple it is to configure the advance settings in the plugin.
