Popular browsers like Chrome and Firefox encourage websites to use the safe HTTPS protocol. However, visitors and owners of websites that use this protocol may see the “This site has insecure content” or Mixed Content error.
Mixed Content Error in WordPress occurs when there is a confliction between SSL and HTTP. Often, its existence doesn't have any effect on the website, but it can negatively affect ranking and SEO.
In the past, using the HTTPS for WordPress websites was optional, but nowadays, it’s necessary to use HTTPS. Running WordPress on HTTPS is an important factor in SEO and ranking. Besides, it makes the website more secure. Because your data is encrypted and it’s no longer in the text format.
In this article, we would like to discuss WordPress's mixed content and how to fix WordPress mixed content.
What is the Mixed Content Error?
The mixed content error occurs when your website is using both HTTP and HTTPS at the same time. In this case, all the content on your website, including texts, images, code, and links are called upon by both HTTP and HTTPS. These protocols are completely different and using them both creates a security breach.
HTTP is the most common connection. However, HTTP is not secure at all and anyone can gain access to your data.
Therefore, using HTTPS is a must. HTTPS creates a secure connection between you and the webserver.
This connection is verified and encrypted. Thus, no one can gain access to your data and almost guarantees the security of the connection. This protocol is a must for generating passwords and online payment methods.
Since 2018, Google Chrome has identified websites that are still using HTTP as insecure and it is heavily encouraging users to visit websites that are using HTTPS/SSL. SSL adds another security layer to your data.
Nowadays, big hosting companies offer free SSL in their packages. If the hosting provider doesn’t offer free SSL and you don’t want to buy it, letsencrypt.org provides free SSL.
If you have installed SSL correctly on your website, a green lock appears next to your website’s URL. This means your website is secure.
