- If payments are not being recorded, make sure that IPN messaging is not disabled in your PayPal setttings. See: PayPal payments not being captured
- If payments are being made but user expiration dates are not being advanced, it may be the listener type. See: Changing the IPN Listener type
- If after clicking the PayPal payment button you receive a message that says “Things don’t appear to be working at the moment”, that generally indicates that your PayPal settings are set to require encrypted buttons. Because the PayPal payment button is generated dynamically so that the user information is passed to PayPal with the button, you cannot require encrypted payment buttons. See: PayPal returns the message “Things don’t appear to be working at the moment”
