My webhost has installed an SSL certificate for my website.  When I navigate to the website, it complains about not being secure.  The error shown is **This CA Root certificate is not trusted because it is not in the Trusted Root Certification Authorities store**.

It sounds to me that this is not a problem with the certificate itself, but rather, a problem of incorrect configuration.  The information that authenticates this certificate isn't in all the places it needs to be.

I presume that means on the server, but I'm not 100% sure.  Where is this store?  Thanks in advance.

To **Patrick Mevzek**, thank you.  I'm looking for the kind of SSL that doesn't require the user to do anything extra.  For example, I don't know how to import the correct CA to the correct store in my browser, and the idea of importing anything from a site that my browser tells me it isn't secure doesn't sound so appealing.

In response to **Stephen Ostermiller's** comments:  Thank you too.
You can visit the site yourself, if that helps: mens.tysonscup.com
I got the certificate from ZeroSSL, but I don't see that mentioned anywhere.
