The SSL Certificate we found on this site is not meant for [your_domain_name], probably this is another site on the same server

apache-2.2ssl-certificate

Note: in this post, I changed my actual domain name to [your_domain_name] to make it more generic.

I installed an SSL certificate for apache2 on my linux server. The certificate's type is "positivessl wildcard". I bought it on namecheap. So far, I know it is working just fine on Chrome and Safari for Mac. However, Firefox (for Mac) will issue a warning message of the kind that is not acceptable: This Connection is Untrusted. Under "Techical Details", it says:

[your_domain_name] uses an invalid security certificate. The
certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)

I submitted my domain name to networking4all.

It says:

Error while checking the SSL Certificate!!

The SSL Certificate we found on this site is not meant for
[your_domain_name], probably this is another site on the same server.

We advise you not to submit any confidential or personal data to this
website because a secure connection could not be established with this
website.

I don't know what that means and I have no idea how to fix it.

Does anyone know what I need to do to solve this? Do I need to issue a new certificate. The thing I am particularly nervous about is: is the certificate busted forever and do I have to buy an entirely new one? Is it a configuration error in apache2?

Thank you very much in advance for your help!

It sounds like you forgot to install the intermediate certificates.

A copy of these should have been included with your certificate, named ca-bundle or something similar. If not, download this from Comodo. Place it on your server, and set its location in Apache's SSLCertificateChainFile directive.
