WHMCS MU is not creating a site

Hi, I have been successful in getting to the payment part in WHMCS for creating test site. I have it set to create the site when payment is received. I manually confirm payment, and then I get this error Module Create Failed - Service ID: 14 - Error: Invalid data or no response: The receiving plugin may not be activated at: https://jeff.jdasmarketing.com Any recommendations would be helpful. Thank you for your time. Jeff
