If you have seen errors related to “Mixed Content”, then this guide will help you understand what this means and how to fix it! We will discuss Mixed Content and the risks involved in it.
Mixed Content is content on a secured site which is not secure. For a secured/encrypted website; its content such as text, images, videos, objects, scripts, link, iframe, etc… that is being delivered over HTTP instead of HTTPS. If any of content loads over HTTP or mixed with HTTP & HTTPS, it is called Mixed Content – or partially encrypted content.

Everything about SSL Mixed Content Error in Chrome
How Browsers Identify ssl Mixed Content?
If a secured page is loaded on any browser, it will check for secured (HTTPS) and non-secured content (HTTP) on that page. If it finds any non-secured content (HTTP) the browser will display mixed content error.
Please note this only affects resources (images, videos, scripts, CSS, etc) that are loaded. If you have links in your page that are specifying HTTP,
Web sites with no warning indicate all the content is secured with SSL. If there is Mixed Content, the security warning indicates the website is partially secured and vulnerable to MITM (Man in the Middle Attack) and insecure content transmission.
What are the Risks involved in Mixed Content?
Mixed content with HTTP puts a user at risk of an MITM attack, which lets attackers modify the content which may put users in trouble if a resource is replaced with harmful code or is captured by an unauthorized party. This presents a clear risk of data breach and identity theft. Attackers can steal user’s credentials, personal & sensitive and financial information as well.
Google will introduce Chrome version 43 with a new feature which lets website developers ensure that their website is running over HTTPS and not compromised by any HTTP insecure resources.

The only solution is encrypting all your website content with HTTPS. This requires you to comb through your HTML and remove/change and references to HTTP. For instance, any images, videos, javascript, css, etc that is linked to via HTTP needs to be updated to be protocol relative, or specify HTTPS. For a secured website if there is no HTTP then you are safe.
