Why is Your WordPress Media Library Not Loading?

The WordPress Media Library serves as a central repository for all the media files you’ve uploaded to your site, from images and videos to audio clips and more. When it’s not loading, it can be a significant concern, especially if you rely on it for content creation and management. Several factors might be causing the Media Library not to load. Let’s delve into some of the most common reasons:

  1. Browser Issues: Sometimes, the problem isn’t with WordPress but with the browser you’re using. Cached data or cookies might be corrupt or outdated, leading to loading issues.
  2. Plugin Conflicts: WordPress is known for its vast ecosystem of plugins. While these plugins can enhance your site’s functionality, they can also interfere with each other or core WordPress functions. A recently installed or updated plugin might be causing a conflict that affects the Media Library.
  3. Theme Conflicts: Just like plugins, the theme you’re using can sometimes have code that conflicts with the Media Library, especially if the theme hasn’t been updated or is not compatible with the latest version of WordPress.
  4. Server Limitations: WordPress runs on a server, and sometimes server-side limitations, such as reaching the PHP memory limit or execution time limit, can disrupt certain functionalities, including the Media Library.
  5. File Permission Issues: For the Media Library to function correctly, WordPress needs specific file and folder permissions on the server. If these permissions are set incorrectly, it can prevent the Media Library from loading.
  6. Corrupt .htaccess File: The .htaccess file is a configuration file for use on web servers. If it becomes corrupted or is misconfigured, it can lead to various issues, including problems with the Media Library.
  7. Outdated WordPress Version: Running an older version of WordPress can result in incompatibilities and conflicts, especially if plugins and themes are updated to be compatible with newer versions of WordPress.
  8. Content Delivery Network (CDN) Issues: If you’re using a CDN to serve your media, there might be issues or conflicts between the CDN and WordPress, leading to the Media Library not displaying correctly.
  9. Unsupported File Formats: If you’re trying to upload a file format that WordPress doesn’t support, it might appear as though the Media Library isn’t loading or functioning correctly.

Understanding the root cause is the first step in addressing the issue. By systematically checking each of these potential culprits, you can identify the problem and take steps to rectify it, ensuring your Media Library is functioning optimally.

define('WP_MEMORY_LIMIT', '256M');

You can replace '256M' with the desired memory limit. Common values include '128M', '256M', or even '512M'.

Save Changes: Save the file after adding the line. Make sure you don’t introduce any syntax errors while editing.

Check the Result: After saving the changes, check if the new memory limit is applied. You can do this by logging into your WordPress admin panel, navigating to “Tools” > “Site Health” > “Info”, and looking for the “Server” section. Here, you should see the new memory limit value.

Disable mod_security in .htaccess

To disable mod_security in your WordPress site using the .htaccess file, you can follow these steps:

  1. Accessing the .htaccess File: Connect to your website’s server using an FTP client or through your hosting control panel. Navigate to the root directory of your WordPress installation, where you’ll find the .htaccess file.
  2. Backing Up Your .htaccess File: Before making any changes, it’s recommended to create a backup of your existing .htaccess file. This will ensure you can easily revert any changes if needed.
  3. Editing the .htaccess File: Open the .htaccess file using a text editor. You can use any plain text editor, such as Notepad (Windows), TextEdit (Mac), or a code editor like Visual Studio Code. How to fix WordPress Media Library not Loading

Disabling mod_security: To disable it, you can add the following lines of code to your .htaccess file:

<IfModule mod_security.c>
   SecFilterEngine Off
   SecFilterScanPOST Off
  1. Place these lines at the beginning of your .htaccess file, just below the RewriteEngine On line if it’s present.
  2. Save and Upload: After making the changes, save the .htaccess file. If you were editing it locally, upload the modified file back to your website’s root directory using your FTP client.
  3. Clear Browser Cache: Clear your browser’s cache and cookies or open your site in a private/incognito window to ensure that the changes take effect.

It’s important to note that while disabling mod_security might be necessary in some cases, it can also impact the security of your website. mod_security is a web application firewall that helps protect your site from various types of attacks. Disabling it could potentially expose your site to security vulnerabilities.

If you’re facing issues with mod_security triggering false positives or interfering with the normal operation of your WordPress site, it’s recommended to work with your hosting provider’s support team or a professional developer to find a more targeted solution that maintains a balance between security and functionality.

Check Your File Formats

Checking file formats is essential because WordPress’s media library requires supported formats for proper display and functionality. Unsupported formats can cause issues like the media library not loading, image display problems, and potential security risks. Make sure you’re uploading supported file types like JPEG, PNG, and GIF for images, and MP4 for videos.


A malfunctioning Media Library can disrupt your workflow and limit your ability to effectively manage your WordPress site. However, by systematically checking each of these potential issues, you should be able to identify and fix the problem, getting your Media Library back in working order.
