I’ve faced many website problems, but the “mixed content” error always surprised me. It can hurt your site’s security and SEO. But don’t worry, I’m here to help you fix it.
We’ll explore mixed content errors in this guide. We’ll look at why they happen and how to solve them. This guide is for everyone, whether you’re new or experienced with WordPress.
Let’s get started on fixing mixed content errors. We’ll make your WordPress site safe and easy to use. It will shine online, free from security issues.
Understanding Mixed Content Errors in WordPress
Keeping your WordPress site safe is very important. A common problem is the mixed content error. This happens when your site uses a secure HTTPS connection but some assets, like images, are loaded over HTTP.
What Causes Mixed Content Warnings
There are many reasons for mixed content errors. These include expired SSL certificates, plugins or themes that use HTTP links, and absolute paths for static assets. These issues can cause browser alerts and a broken padlock icon. This can hurt your site’s trust and search rankings.
Impact on Website Security and SEO
Having insecure content on an HTTPS site is very bad. Google Chrome shows big warnings for mixed content. This can make users lose trust and hurt your SEO.
Types of Mixed Content Issues
- Passive mixed content: This means non-interactive assets like images and videos that are loaded over HTTP.
- Active mixed content: This includes interactive things like scripts and forms that are loaded over HTTP.
Both types of mixed content can cause browser alerts. This can hurt your site’s user experience and search rankings.
Why Mixed Content Errors Occur After SSL Installation
Switching your website to HTTPS makes it safer and more trustworthy. But, you might see “mixed content errors” even with an SSL certificate. These happen when a secure page has both secure (HTTPS) and non-secure (HTTP) stuff, like images or scripts.
Hard-coded HTTP URLs in your site’s database or theme files cause these errors. These URLs stop your site from loading fully over HTTPS. This leads to mixed content warnings.
Outdated plugins or not fully migrating to HTTPS also cause problems. When you switch to SSL, make sure all content, including third-party stuff, loads over HTTPS.
To fix mixed content issues, you need to set things up right. This means updating WordPress, tweaking your .htaccess file, and checking your theme and plugins for HTTPS support.
How to Fix Mixed Content Error in WordPress
Fixing mixed content errors in WordPress can be tricky. But, with the right tools and strategies, you can fix it. First, use your browser’s developer tools to find the problems.
Using Developer Tools to Identify Issues
Browser developer tools are great for finding mixed content errors. Firefox, Chrome, and other browsers have these tools. They help you see what’s wrong on your WordPress site.
Common Problem Areas
- Media Library: Make sure all images, videos, and media are loaded over HTTPS.
- Theme Files: Check your theme’s CSS and JavaScript files for HTTP links that need updating.
- Plugin Settings: Some plugins might reference HTTP resources. Update these settings.
Prevention Strategies
To stop mixed content errors, try these:
- Use Relative URLs: Use relative URLs for your site’s resources. This ensures content loads securely.
- Keep Your WordPress Site Updated: Regular updates fix mixed content issues. Developers often solve these problems in updates.
- Implement Content Security Policies: A Content Security Policy (CSP) helps secure resource loading. This reduces mixed content errors.
Fixing mixed content errors in WordPress needs careful testing. But, with the right tools and strategies, your site will load securely. Use your browser developer tools and fix common problem areas. Also, use prevention strategies to keep your site healthy and free from mixed content errors.

Manual Database Updates for HTTP to HTTPS Conversion
If your WordPress site has mixed content errors after getting an SSL certificate, try updating your database manually. Use a search and replace tool to change “http://” to “https://” in your database.
Using Better Search Replace Plugin
The Better Search Replace plugin is great for this job. It helps you change HTTP URLs to HTTPS in your database. Always backup your database first, just in case.
- Install and activate the Better Search Replace plugin in your WordPress dashboard.
- Navigate to Tools > Better Search Replace.
- In the “Search for” field, enter “http://”.
- In the “Replace with” field, enter “https://”.
- Select the relevant tables you want to update, such as the “wp_posts” and “wp_postmeta” tables.
- Enable the “Dry run” option to preview the changes before applying them.
- Click “Run Search/Replace” to execute the update.
Database Backup Precautions
Always create a backup before updating your database. This way, you can go back if something goes wrong. Use a plugin like UpdraftPlus or BackWPup for a good backup.
Verifying Changes
After updating, make sure to verify the changes. Check your website’s content and how it works. Make sure all HTTP URLs are now HTTPS.
By doing these steps, you can fix hard-coded HTTP URLs in your WordPress site. This will help you get rid of mixed content errors and make your site fully secure.
Modifying .htaccess File for HTTPS Enforcement
Changing the .htaccess file can fix WordPress’s mixed content problems. This file is in your WordPress’s root directory. It handles server settings, like website redirects.
Adding special rewrite rules to the .htaccess file can redirect all HTTP requests to HTTPS. This makes your whole website secure. It also fixes mixed contents warnings and makes your WordPress site safer.
- Open the
.htaccessfile in your WordPress’s root directory. - Add these lines to the file:RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
- Save the
.htaccessfile and put it back on your server.
These commands tell the Apache server to send all HTTP requests to HTTPS. This makes sure your WordPress site is always secure. This Apache server configuration and WordPress HTTPS redirection fix mixed contents errors.
It’s important to check your website well after these changes. Make sure the WordPress HTTPS redirection works right and no new problems came up.
Updating WordPress Settings and URLs
Moving your WordPress site from HTTP to HTTPS makes it safer for visitors. You must update your site’s URL and home URL to HTTPS. This change is key for a secure browsing experience.
In your WordPress general settings, change the WordPress site URL and home URL to HTTPS. This makes sure all links on your site are secure. It also stops mixed content errors.
- Log in to your WordPress dashboard and go to the Settings > General section.
- Change the “WordPress Address (URL)” and “Site Address (URL)” fields to start with “https://”.
- Save your changes in the general settings.
After updating, clear your website’s cache. This makes sure the HTTPS change works everywhere on your site. It’s important for a secure site and to avoid mixed contents problems.
Updating your WordPress site URL and home URL to HTTPS makes browsing safer for your visitors.
It’s important to check and update your WordPress settings often. This keeps your site healthy and secure.
Checking Theme and Plugin Compatibility
When you move your WordPress site to HTTPS, check if your theme and plugins work well. If they don’t, it can cause problems like mixed contents errors. This can hurt your site’s security and how it works.
Common Plugin Conflicts
Plugins not made for HTTPS can cause trouble when you turn on SSL. You might see mixed content warnings or broken images. It’s key to find and fix any plugin issues to make HTTPS work smoothly.
Theme-Related Issues
Just like plugins, your WordPress theme might have HTTP URLs in it. These need to be changed to HTTPS to avoid mixed content errors. Themes that don’t work with HTTPS can also cause layout problems or broken features.
To fix theme and plugin problems, follow these steps:
- Make sure all your WordPress themes and plugins are up to date. This helps with HTTPS support.
- Turn off and delete any plugins you don’t need. They might get in the way of your HTTPS setup.
- Choose a new theme that is explicitly made to work with SSL/HTTPS.
- Use the SSL Insecure Content Fixer plugin to find and fix mixed contents problems.
By making sure your WordPress theme and plugins work with HTTPS, you can avoid mixed content errors. This keeps your site safe and working well for your visitors.
Implementing Content Security Policies
We work hard to keep our WordPress sites safe and sound. One key step is using content security policies (CSP). CSP stops mixed contents problems, which can happen after getting an SSL certificate.
With CSP, we pick where our site can get content from. This includes scripts, styles, images, and more. It makes sure our site only gets resources from safe places. This helps avoid security risks and keeps our site safe.
Using web security headers and CSP helps prevent mixed content. It makes sure all content is loaded over HTTPS. This makes our site more secure and shows a “Secure” padlock in the browser.
To start with CSP implementation, we can use WordPress plugins or set HTTP headers manually. By doing this, we make our site safe for visitors. We also meet modern web security standards.
“Implementing content security policies is a key step in keeping your WordPress site safe and secure.”
Troubleshooting Common SSL Certificate Issues
As a WordPress site owner, I’ve faced many SSL certificate problems. These include expired certificates and domain name mismatches. But, with the right steps, I’ve solved these issues quickly.
One big problem I’ve seen is the “NET::ERR_CERT_INVALID” error. This usually means there’s a problem with the SSL certificate.
To fix this, I make sure my SSL certificate is valid and matches my domain name. I also check if the intermediate SSL certificates are set up right. This helps avoid mixed content warnings, even with a valid SSL certificate.
Setting up SSL correctly is key for security and trust. I check my SSL certificate’s expiration and renew it on time. This keeps my site’s secure connection running smoothly.
By keeping up with SSL issues, I offer my visitors a safe and easy browsing experience. This is important for keeping their trust and following web standards.
