Lock not showing on main page-zencart

apache2-ubuntu-vps server-zencart 1.1.5
I’ve installed comodo certs on my site <jamisoncorp.com> I have set http server to point to https, when I go to my site the logo will not appear and I’m in http. If I click on a link in the store it changes the entire site to https including the main page. What am I missing to enable comodo when a customer first comes to my site?

It seems to be working fine when I load it on Firefox, and I ran it through an SSL checker, which didn’t turn up any errors. What you might want to do to help force connections to be secure is add an HSTS header to your site and submit it to the preload list. Once you’re on the list, your customers’ browsers will know to make a secure connection on their first visit and on every subsequent visit.
