PROBLEM
Error in Internet Explorer: "Only secure content is displayed" when you try to load a page with the HTML5 Viewer.


SOLUTION 
The HTML5 Viewer is a client-side widget consisting of Kendo UI widgets and functionality for communicating with a Telerik Reporting RESt service instance. The Ui and the functionality are added via JavaScript and CSS files loaded on the same page.

If you use an IFRAME element to load the page with the HTML5 Viewer, and all requests are issues over HTTPS, the error can occur due to a left link that uses HTTP.

The issue can be detected by running the page in Internet Explorer with opened Console (F12 Developer Tools). In the error logs you will see a message like:
 This will hint you which CSS/JS file is requested over HTTP.
