Mixed Content
What This Means
HTML pages loaded over a secure HTTPS connection that have resources such as images, JavaScript or CSS that are loaded via an insecure HTTP connection. Mixed content weakens HTTPS, and makes the pages easier for eavesdropping and compromising otherwise secure pages. Browsers might automatically block the HTTP resources from loading, or they may attempt to upgrade them to HTTPS.
What Triggers This Issue
This issue is triggered when a HTML page loaded over a secure HTTPS connection contains resources such as images, JavaScript or CSS, that are loaded via an insecure HTTP connection. For example: https://www.getasky.com/ Contains the image: http://www.getasky.com/froggy.jpeg
How To Fix
All HTTP resources should be changed to HTTPS to avoid security issues, and problems loading in a browser.
