    This is an issue with your PayPal API Settings in your payment field.

    Please, make sure that you are entering the correct API username, password, and signature.

    I would suggest that you can use test integration button in the Payment Wizard, by clicking that one to test out if the integration is working or not.



    Here's how you can get your Paypal Pro API Credentials: https://developer.paypal.com/docs/classic/api/apiCredentials/#creating-classic-api-credentials 

    If you have any question or issues, please do not hesitate contacting us. We will be glad to assist you.
