The certificates should be pasted in the following sequence, your site Certificate named yourdomain.cer, Digi-SignCADigi-SSLXp.crt or Digi-SignCADigi-SSLXs.crt , UTN-USERFirst-Hardware.crt, and the resulting file should look like the following:
-----BEGIN CERTIFICATE-----
(Class3CertificateAthority Encoded Text)
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
(TrustRootCertificateAuthority Encoded Text)
-----END CERTIFICATE-----
Please note: Make sure you include the -----BEGIN CERTIFICATE----- and -----END CERTIFICATE----- as displayed above.
