This website does not supply ownership information
This message simply refers to the fact that the certificate is domain-validated (DV) rather than OV or EV. It is not an error.
However, your website does not properly send the full certificate chain (it is missing the intermediate certificate) which is why it may appear insecure in some browsers.
It depends on how you acquired the certificate, but you will need to add the intermediate certificate to the Apache config, such as is shown in this post: [Solved] Why isn't my certificate trusted? - #2 by germeier
