Web Page Panel shows up as blank in Chrome.

Web Page Panel shows up as blank in Chrome.

If you have insecure (HTTP) content being loaded into a secure (HTTPS) page or frame, it may be blocked. In this case, Web Player analysis may be accessed using HTTPS and the page in the Web Page Panel  accessed using HTTP. In Internet Explorer (IE) there is an option to show insecure content, however it seems to be silently blocked in Chrome. The error can be seen when using the Developer Tool (F12) in Chrome.

This appears to be a mixed content issue.
For Google Chrome,
- If you want to disable mixed content for this session only, click the shield icon. Then click on the "Load unsafe script" button. 
- If you want to disable mixed content for all future sessions on all sites, add a command-line flag to Chrome: --allow-running-insecure-content.
