This is Why Your WordPress Scripts Aren't Loading Because of SSL (And How to Fix It)
If you've set up an SSL certificate for your WordPress site, you may have encountered some issues with your scripts (like JavaScript files) not loading properly. This can lead to a poor user experience, broken functionality, and even security vulnerabilities on your website.
The good news is that there are some straightforward steps you can take to resolve these problems and ensure your scripts load correctly over HTTPS. In this article, we'll dive into the common reasons why WordPress scripts might not be loading due to SSL, and provide you with practical solutions to get your site back up and running smoothly.
Understanding the Issue: Why Scripts Don't Load Over HTTPS
When a user visits your WordPress site over HTTPS, their browser expects all resources (including scripts, images, CSS files, etc.) to be served securely over the same encrypted connection. If any of those resources are loaded over an insecure HTTP connection, the browser will block them for security reasons.
This is a common problem on WordPress sites that have recently migrated to HTTPS, or where the SSL configuration wasn't set up properly from the beginning. There are a few key reasons why this can happen:
-
Mixed Content: If your WordPress site includes any resources (scripts, images, etc.) that are loaded from an HTTP URL, this is known as "mixed content." The browser will block these insecure resources to protect the user's security and privacy.
-
Hardcoded HTTP URLs: Sometimes, WordPress themes, plugins, or custom code may have hardcoded HTTP URLs for scripts and other assets. This will cause them to fail to load over HTTPS.
-
Plugin or Theme Conflicts: Certain WordPress plugins or themes may not be properly configured to work with HTTPS, leading to script loading issues.
-
Caching Issues: If you have caching enabled on your WordPress site, the cached versions of your pages may still reference HTTP URLs for scripts, even after you've switched to HTTPS.
-
DNS or Hosting Configuration Problems: Issues with your DNS settings or web hosting configuration can also prevent scripts from loading correctly over HTTPS.
Identifying and addressing these underlying problems is crucial to resolving the "scripts not loading because of SSL" issue on your WordPress site. Let's take a look at how you can do that.
How to Fix WordPress Scripts Not Loading Due to SSL
Here are the steps you can take to troubleshoot and fix the problem of WordPress scripts not loading because of SSL:
1. Check for Mixed Content
The first step is to identify any mixed content issues on your WordPress site. You can use a tool like the W3C Mixed Content Checker to scan your site and detect any resources that are being loaded over HTTP.
Alternatively, you can use your browser's developer tools to identify mixed content issues. In Google Chrome, for example, you can open the developer tools (F12 or Ctrl+Shift+I), navigate to the "Network" tab, and look for any resources that are being loaded over HTTP.
Once you've identified the problematic resources, you'll need to update them to use HTTPS URLs. Depending on the source of the mixed content, you may need to:
- Update the URLs in your WordPress theme's code or any custom code you've added.
- Check your plugins and themes for any hardcoded HTTP URLs and update them.
- Update any external scripts or resources you're including from third-party domains to use HTTPS.
2. Ensure Your WordPress Site is Fully Configured for HTTPS
Next, you'll want to make sure your WordPress site is properly configured to use HTTPS. Here are some steps to take:
-
Update WordPress Site URL: In the WordPress admin dashboard, go to "Settings" > "General" and ensure that both the "WordPress Address (URL)" and "Site Address (URL)" fields are set to the HTTPS version of your site.
-
Update .htaccess File: Add the following code to your WordPress site's .htaccess
file to force HTTPS:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
This will automatically redirect all HTTP traffic to the HTTPS version of your site.
- Verify SSL Configuration: Use a tool like the SSL Labs Server Test to check the SSL configuration of your WordPress site and ensure it's set up correctly.
3. Clear Caching and Browser Cache
If you're still experiencing issues with scripts not loading, it could be due to caching. Clear the cache on your WordPress site, as well as the cache in your web browser, to see if that resolves the problem.
In WordPress, you can use a caching plugin like W3 Total Cache or WP Rocket to clear the cache. For your browser cache, simply clear the cached files and reload the page.

4. Deactivate and Reactivate Plugins
Certain WordPress plugins may not be properly configured to work with HTTPS, which can cause script loading issues. Try deactivating and then reactivating any plugins that might be causing the problem.
You can also try disabling all plugins and then re-enabling them one by one to identify the culprit. This will help you pinpoint any plugin-related conflicts.
5. Update WordPress, Themes, and Plugins
Ensure that your WordPress installation, as well as any themes and plugins you're using, are up to date. Outdated software can sometimes lead to compatibility issues with HTTPS, which may prevent scripts from loading correctly.
6. Check Your Hosting Configuration
If you've followed all the above steps and are still experiencing issues, the problem may lie with your web hosting configuration. Speak with your hosting provider to ensure that your server is properly configured to handle HTTPS traffic and that there are no conflicts or issues on their end.
7. Use a Content Delivery Network (CDN)
Incorporating a Content Delivery Network (CDN) into your WordPress setup can also help resolve script loading issues due to SSL. A CDN can help ensure that your scripts and other static assets are delivered quickly and securely over HTTPS, regardless of the user's location.
Popular CDN providers for WordPress include Cloudflare, KeyCDN, and Sucuri. Setting up a CDN may require some technical configuration, but it can significantly improve the performance and security of your WordPress site.
Conclusion: Troubleshoot and Fix WordPress Scripts Not Loading Due to SSL
Ensuring that all your WordPress scripts and resources load correctly over HTTPS is crucial for providing a seamless user experience and maintaining the security of your website. By following the steps outlined in this article, you should be able to identify and resolve the root causes of any script loading issues related to SSL.
Remember, a data-driven approach is key to effectively troubleshooting and fixing these problems. Use tools like the W3C Mixed Content Checker, browser developer tools, and website performance testing services to gather the necessary data and insights to guide your troubleshooting efforts.
