My web server is (include version): (Info from hosting service) Perl 5.24.1 PHP 5.2.17
The operating system my web server runs on is (include version): Debian GNU/Linux (doesn't give version)
My hosting provider, if applicable, is: us.cloud
I can login to a root shell on my machine (yes or no, or I don't know): I don't know
I'm using a control panel to manage my site (no, or provide the name and version of the control panel): No
The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot): I don't know. us.cloud installed the certificate
Thank you for such a quick response and the site links, which I did not know about. I'm glad to hear that the certificate is fine. I will take a look at the results and see if I can figure out what to change on my site. This is my first go with a certificate, and I'm discovering just how much I don't know.
Thanks, Griffin. I see now: there are two types of mixed content. I took care of the active ones, but there are still passive ones. (Again, all new territory for me.) I will go back and take a look.
