    I have 4 files sent to me by comodo which include the 2  mentioned files, AddtrustexternalCAroot file and a certificate file.

    The first 3 are .crt files. the last file is a .cer files.

    Plesk requires the following formats

    1. Private key -      *.key

    2. Certificate         *.crt

    3. CA Certificate    *-ca.crt

     

    Help please, how do I match the Comodo provided files to required Plesk format as listed above.

    I am very confused.

    Comodo gives you four files:

    AddTrustExternalCARoot.crt
    COMODORSAAddTrustCA.crt
    COMODORSADomainValidationSecureServerCA.crt
    STAR_csa_one.crt

     

    You need the two files:
    1.STAR_csa_one.crt
    2.COMODORSADomainValidationSecureServerCA.crt


    In Plesk (17.08)

    For a Serverwide Certificate go to:
    HomeTools & Settings>SSL/TLS Certificates (the one with the CSR you created)

    For Domain specific Certificate:
    Home> Domains> "your domain">SSL/TLS Certificates (the one with the CSR you created)

    Below it says:
    Upload the certificate files
    Use this form to upload the components of a certificate as constituent files.

    Certificate (*.crt) * choose File:
    STAR_csa_one.crt

    CA certificate (*-ca.crt) choose File: COMODORSADomainValidationSecureServerCA.crt
