Invalid attestation format from your own demo page

[kopeboy]

I clicked on "new registration", clicked create in the browser alert and received "invalid atttestation format: none"

well this is because you have not selected none at the bottom, basically whatever thing you are registering is not sending any attestation or you are blocking the attestation going through, therefore it gets no attestation

what are you trying to register with?
