Hello,
When I changed the settings in the configuration.php file on your site earlier it was loading all the Template files in https:// format as well as the google font files here:
<script type="text/javascript" src="https://www.shiftev.com/templates/traction/js/s5_flex_menu.js"></script>
<link rel="stylesheet" href="https://www.shiftev.com/templates/traction/css/s5_flex_menu.css" type="text/css" />
<link rel="stylesheet" href="https://www.shiftev.com/templates/system/css/system.css" type="text/css" />
<link rel="stylesheet" href="https://www.shiftev.com/templates/system/css/general.css" type="text/css" />
<link href="https://www.shiftev.com/templates/traction/css/template_default.css" rel="stylesheet" type="text/css" />
<link href="https://www.shiftev.com/templates/traction/css/template.css" rel="stylesheet" type="text/css" />
<link href="https://www.shiftev.com/templates/traction/css/com_content.css" rel="stylesheet" type="text/css" />
<link href="https://www.shiftev.com/templates/traction/css/editor.css" rel="stylesheet" type="text/css" />
<link href="https://www.shiftev.com/templates/traction/css/thirdparty.css" rel="stylesheet" type="text/css" />
I am not 100% sure if changing the certificate will affect any of the other files or not since from what I can tell your certificate is considering files loaded on the same server as the site insecure.
