Understanding Mixed Content
Definition of Mixed Content
Mixed content refers to a situation in which a website contains both secure (HTTPS) and non-secure (HTTP) elements. When a webpage is served over HTTPS, all of its content should also be served over HTTPS in order to maintain a secure connection between the website and its visitors. Mixed content can occur when certain web elements, such as images, scripts, or stylesheets, are loaded using HTTP instead of HTTPS, which can pose a security risk.
Why it is an Issue
Having mixed content on your WordPress website can present several issues. Firstly, it can compromise the security and privacy of your users, as the presence of any non-secure elements on an otherwise secure webpage can potentially expose sensitive information. Additionally, modern web browsers often block non-secure content, which can negatively impact the user experience. To ensure the integrity and security of your website, it is crucial to identify and address any mixed content issues.
Identifying Mixed Content on WordPress
Using Browser Developer Tools
One way to identify mixed content on your WordPress site is by using the developer tools provided by modern web browsers. These tools allow you to inspect the various components of a webpage, including its resources and network requests. By examining the network requests made by your website, you can easily identify any HTTP resources that might be causing mixed content issues. Browsers like Google Chrome and Mozilla Firefox offer developer tools that can be accessed by right-clicking on a webpage and selecting the “Inspect” option.
Understanding Error Logs
Another approach to identifying mixed content on WordPress is by checking the error logs generated by your website. Error logs can provide valuable insights into any issues or warnings related to mixed content. Typically, error logs can be accessed through your WordPress hosting cPanel or via FTP. Look for any warnings or errors related to insecure content or mixed content, which can guide you in locating and resolving the issue.
Handling HTTP and HTTPS Content
How to Transition from HTTP to HTTPS
Transitioning from HTTP to HTTPS involves securing your website by obtaining an SSL/TLS certificate and configuring your server to enable HTTPS. This process typically requires assistance from your web hosting provider, as they can help you install the certificate and ensure that your website is properly redirected from HTTP to HTTPS. It is important to follow the recommended steps provided by your hosting provider to ensure a smooth transition without any mixed content issues.
What to Know About Secure and Insecure Content
When transitioning from HTTP to HTTPS, it is crucial to understand the difference between secure (HTTPS) and insecure (HTTP) content. Secure content, such as images or scripts loaded via HTTPS, will not cause any mixed content issues. Insecure content, however, must be addressed to avoid warnings or blocking by web browsers. Ensuring that all resources, including images, scripts, and stylesheets, are served over HTTPS is essential to maintain a fully secure website.
Fixing Hard-coded URLs
Identifying Hard-coded URLs
Hard-coded URLs refer to instances in which the URL of a resource is explicitly specified in the source code of a website, rather than being dynamically determined. To identify hard-coded URLs, you will need to access the underlying source code of your WordPress theme or plugins. Look for any instances of resources, such as images or scripts, being loaded using an insecure (HTTP) URL.
Changing URLs to Use HTTPS
To fix hard-coded URLs, you will need to update them to use HTTPS instead of HTTP. This can be done by replacing the insecure URLs with their secure counterparts. For example, if an image is currently loaded using the URL “http://example.com/image.jpg,” you would need to change it to “https://example.com/image.jpg.” Updating the URLs in the source code will ensure that the resources are loaded securely over HTTPS.

Modifying Images and Media Files
Locating HTTP Images and Media
To locate HTTP images and media files on your WordPress site, you can use various methods. One approach is to use the Media Library within your WordPress admin panel. Here, you can filter the media files by their URL or filename, allowing you to easily identify any resources that are loaded using insecure URLs. Additionally, you can also use a plugin specifically designed to search for and identify insecure images and media files.
Updating to HTTPS
Once you have identified the HTTP images and media files on your WordPress site, you will need to update their URLs to use HTTPS. The simplest approach is to edit each media file individually and replace the HTTP URL with its HTTPS counterpart. However, if you have a large number of media files, using a plugin or script that can automate this process might be more efficient. By updating the URLs to HTTPS, you ensure that the images and media files are loaded securely on your website.
Editing HTTPS Content on WordPress
Modifying WordPress Site Address
To edit the WordPress site address, which includes the URL of your website, you can navigate to the general settings within the WordPress admin panel. Here, you can modify the URLs to use HTTPS instead of HTTP. It is crucial to update both the WordPress Address (URL) and Site Address (URL) fields to ensure that all internal links in your WordPress site use the secure HTTPS protocol.
How to Edit WordPress Config File
In some cases, editing the WordPress configuration file (wp-config.php) might be necessary to handle HTTPS content. This file contains important settings and defines various constants used by WordPress. By adding the necessary code to the wp-config.php file, you can enforce the use of HTTPS throughout your WordPress site. Instructions for editing the file can be found in the WordPress documentation, or you can seek assistance from your web hosting provider.

Handling External Scripts
Finding External HTTP Scripts
To find external HTTP scripts on your WordPress site, you will need to examine the source code of your website. Look for any script tags that reference external resources and check their URLs to determine if they are loaded using HTTP or HTTPS. External scripts include third-party libraries, embedded videos, or any other resources that are not hosted on your own website.
How to Replace External HTTP Scripts with HTTPS
Replacing external HTTP scripts with HTTPS can involve modifying the source code of your WordPress theme or plugins. Locate the script tags that reference the external resources and update their URLs to use HTTPS. If the external resource does not support HTTPS, consider finding an alternative or hosting the script locally on your own server. By ensuring that all external scripts are loaded securely over HTTPS, you eliminate mixed content issues and enhance the security of your WordPress site.
Updating Content Delivery Network (CDN) Links
What is a CDN?
A Content Delivery Network (CDN) is a network of servers distributed across different geographic locations. It is designed to improve the delivery speed and performance of web content by caching and serving it from the server location closest to the user. CDNs are commonly used to deliver images, videos, scripts, and other static content. When transitioning to HTTPS, it is important to update any CDN links to use HTTPS as well.
How to Replace HTTP CDN Links with HTTPS Links
To replace HTTP CDN links with HTTPS links, you will need to locate the places where the CDN links are being used in your WordPress site. This can include theme files, plugin files, or custom code snippets. Update the URLs of the CDN links to use HTTPS, ensuring that any resources served through the CDN are loaded securely on your website.

Verifying Your Fixes
Re-testing Your WordPress Site
After making the necessary changes to address mixed content on your WordPress site, it is important to re-test your website to ensure that all issues have been resolved. Visit your website using different web browsers and devices to check for any mixed content warnings or errors. Additionally, examine the network requests made by your website using the developer tools to ensure that all resources are loaded securely over HTTPS.
Understanding Potential Issue Recurrence
While addressing mixed content issues is essential, it is important to understand that the recurrence of such issues can happen due to various factors. Updates to plugins, themes, or any changes made to the source code of your WordPress site can introduce new insecure URLs. It is crucial to regularly monitor your website and perform periodic checks to identify and address any potential mixed content issues that may arise in the future.
By following the steps outlined above, you can effectively identify and fix mixed content issues on your WordPress site without relying on plugins. Ensuring that your website is fully secured with HTTPS not only protects the privacy and security of your users but also enhances the overall user experience. Regularly monitoring and maintaining your WordPress site will keep it free from mixed content issues and ensure a safe browsing experience for all your visitors.
