I am a newbie in SSL certificates and was given the task on troubleshooting a site's WHM page that uses https but it displays an red "x" on the https section of the URL.

On Google Chrome, details of the error says: 

Root certificate authority
Expires: Tuesday, May 5, 2015

then down below it says:

This root certificate is not trusted

On Firefox, details of the error says:

<sitename> uses an invalid security certificate. 
The certificate is not trusted because it is self-signed. 
(Error code: sec_error_unknown_issuer)

What should I do? Thanks in advance.

    Buy a certificate signed by a trusted CA and install it.

When you install Service SSL Certificates in WHM, you're showing the users of your server that you are who you say you are. When you use self-signed certificates, there's no authority that attests to the correctness of the certificate's information. This causes a trust warning in the browser, telling users that they may not be dealing with whom they wish.

More information can be found about self-signed certs here: http://en.wikipedia.org/wiki/Self-signed_certificate

There are many CA's (Certificate Authorities) who can provide SSL certs at a reasonable price. Shop around and find one that satisfies your needs. Comodo is an example of a CA that offers bargain pricing on their basic certs.

  • Thanks for the answer. I know know that self signed certs is not that secure and third party CA is much better.
