HTTPS Security Error Messages

If you are working on a task to investigate HTTPS security errors, the chances are that there has been a file uploaded to a site that was previously not HTTPS, but has since been updated to this standard.

To find out the cause of the security issue, you can run the site with the errors locally and press F12 for the developer tools to appear. In here select Console to give you an idea of what is causing the problem.

This should help get you to a diagnosis of the issue.
