Mixed Content Handling: Google Chrome and Internet Explorer
By default, Google Chrome and IE block unsecure content on SSL encrypted pages. For example, if an encrypted Moodle page has content loaded from an unencrypted page over http (a video, for example), the content will not appear unless the user specifically allows the mixed or unsecure content. The prompt was prominent until the new version of Google Chrome (and still is in IE). Students and instructors using the newest version of Chrome will likely be unable to determine how to allow the blocked content.
Google Chrome Solution
The prompt for allowing blocked content is now a small grey shield icon in the address bar. Clicking this icon and selecting the “Load Anyway” link will refresh the page with the unencrypted content presented.

Internet Explorer Solution
Some web sites allow you to access it using the secure connection (https), yet show both the secure (https) and insecure (http) content. If you access such a web site using the Microsoft Internet Explorer web browser, you might get a warning prompt—only secure content is displayed. This is because that web site is showing mixed content—both the secure (https) and insecure content (http). You have to choose to display mixed content each time you visit such a site. If you want, you can enable display of mixed content permanently, here is how:
- In Internet Explorer, click the Tools button, and then click Internet Options.
- Click the Security tab, and then click the Custom Level button.
- In the Security Settings dialog box, scroll to the Display mixed content setting in theMiscellaneous section, and then click Enable. Normally this will be at Prompt.
- Click OK in the Security Settings dialog box, and then click OK to exit Internet Options.
Refresh Your Page Content
First try refreshing your page. If that does not work, then clear your cache.

PC: navigate to the page and press the F5 key
