What is Mixed Content Error in WordPress?

It is highly recommended to add HTTPS / SSL in WordPress because after July 2018 Google Chrome will mark all http versions of website as insecure.

SSL adds an additional security layer around data transferred from your website to users’ browsers. Search engines like Google recommend using SSL on your website as well.

All best WordPress hosting companies are now offering free SSL as part of their packages. If your hosting company doesn’t offer that, then you can get free SSL through Let’s Encrypt for your WordPress site.

If you have correctly implemented SSL on your website, then you will see a green padlock icon next to your website’s URL in the browser address bar.

On the other hand if your HTTPs/SSL settings are not properly setup, then you will see an info sign or a broken padlock icon in the address bar.

Not fully secure due to mixed content

This indicates that while your website is using a SSL certificate, some content on your website is still served from non HTTPS urls.

You can find out which content is served through insecure protocol by using the Inspect tool. The mixed content error will be displayed as a warning in the console with details for each mixed content item.

If it is just a single item that you can manually fix, then you can go ahead and fix it by editing the post, page, or theme file where it appears.

However, in most cases these items are added dynamically by WordPress or stored in your database. In that case, it will be hard to detect all of them and fix them manually.

That being said, let’s take a look at how to easily fix the mixed content error in WordPress.

Fixing Mixed Content Error in WordPress

First thing you need to do is install and activate the SSL Insecure Content Fixer plugin. For more details, see our step by step guide on how to install a WordPress plugin.

3. Widgets

This includes all fixes applied in content level plus an additional fix to resources loaded in all WordPress widgets on your website.

5. Capture all

  5. What happens when you want to display insecure links on your secure site but the SSL certificate is preventing them from showing?

    I want to include links to California’s Caltrans traffic cams on my site but since they’re insecure, they show up on the backend. No mixed content warnings, it just won’t show them on the front end.

    I can’t just call the state of California and tell them to add security to their traffic cam links, so is there any fix for this?

    • You could use a URL shortener such as Bitly to link to the HTTP link through an HTTPS shortened link
