The browser notifies the wesbite contains both secured (https) and unsecured (http) content

The browser notifies the wesbite contains https and http content.

This message notifies the visitor that (some of) the content of the website is displayed via an unsecured connection. The most common cause is that images are loaded via a prefixed URL with http:// , instead of https://. This happens to other types of content too, like stylesheets and javascripts and also external links like Google Adwords or Analytics. This can be fixed by checking the sourcecode of your website and checking all links to see if these are prefixed with https://.
