Some older courses had custom certificates, those custom certificates are no longer active and so the certificate appears blank except for the user's name and the date of completion. If you check the user's transcript and the certificate is blank except for that information, please escalate so that we can have the DR Administrators update the certificate.

I apologize for the blank certificate that your course has generated. I have viewed your certificate and I can see that only your name and the date are currently showing. I will need to create a ticket so that the site Administrators can update it for you. Please allow me just a moment to do so.
