What causes mixed content warnings?
Causes of mixed content warnings
Plugin developers sometimes use absolute paths (http://yourdomain.com/style.css) in their plugins or themes to link to CSS and JavaScript rather than using relative paths ( /style.css).
Images have hard-coded URLs (http://yourdomain.com/image.png) that point to HTTP. These URLs can be found in a post, page, or even a widget.
You have set up links to HTTP versions of external scripts (Hosted jQuery, Font Awesome, etc.).
You have integrated video scripts using HTTP rather than HTTPS.
