SECTIGO PositiveSSL Installation for Plesk (Certificate Chain, Intermediate Certificate, CA-Certificate)

SECTIGO Knowledge Base offers a detailed tutorial including screenshots https://support.sectigo.com/Com_KnowledgeDetailPage?Id=kA01N000000zFIw

For pro users, the short version below is focusing on the details of the certificate chain:

After validating the SECTIGO certificate request, SECTIGO is delivering your PositiveSSL certificate by email. The email includes an attached ZIP file that contains the following files:

EITHER:

<yourdomain>.ca_bundle
<yourdomain>.crt

OR:

SectigoRSADomainValidationSecureServerCA.crt
USERTrustRSAAddTrustCA.crt 
AddTrustExternalCARoot.crt 

<numbers>.crt


Plesk 12 is only offering two textfields for pasting your certificate. In order to paste your PositiveSSL certificate including the full certificate chain, copy the contents of your "your_domain_com.crt" / "<numbers>.crt" into the field Certificate. The CA-Certificate consists of SectigoRSADomainValidationSecureServerCA.crt appended by USERTrustRSAAddTrustCA.crt.  The following content has to be pasted into the "CA-Certificate" field:
