    Hi Brenda,

    This is an issue with your API Credentials in the Paypal Pro payment field.  Please make sure that you are entering the correct API username, password, and signature. There's a test integration button in the Payment Wizard, I would suggest 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
