    Paypal Pro: Invalid Configuration error when the form is submitted

    Asked by Quick6 on June 03, 2014 at 12:13 AM

    My payments system was working and then it just stopped. I have an event coming up soon and I need this fixed ASAP as it is interupting my business.

    Base on Paypal Error Codes, that problem occurs when the billing agreement is disabled or inactive on your Paypal account (ERROR CODE 10501). Or, when you have not agreed to the billing agreement. Please ensure that you have enabled and agreed to the billing agreement on your PayPal account to be able to process payments.

    In either case you may want to contact PayPal and ensure that your account is set up to process Website Payments Pro transactions and that the billing agreement is accepted.

    If you require any further assistance, feel free to contact us.
