What Is “Failed To Load Resource” Error in WordPress?

The “Failed to load resource” error is common when a browser or server fails to load a specific resource file, such as an image, stylesheet, JavaScript file, or any other asset required by a web page. This error is common to WordPress users and sometimes for WordPress administrators. 

It doesn’t matter where you are seeing this error, it is very important to fix this. Even sometimes it shows when you are performing a task on WordPress such as uploading resource files like images or files.

How “Failed to Load Resource” Appears?

The error message mostly appears in the web browser’s developer console, providing valuable information about the failed request and the resource causing the issue.  Each error message  can be different as it depends on the types of resources used on the website. These could be CSS stylesheet, Javascript, or an image.

Here are a few examples of the “Failed to Load Resource” Errors. The error message may look something like this:

  • Failed to load resource: the server responded with a status of 404 (Not Found)
  • Failed to load resource net::ERR_CONNECTION_REFUSED
  • Failed to load resource: net::err_name_not_resolved
  • Failed to load resource: the server responded with a status of 500 (Internal Server Error)

What are Common Causes for This Error?

Incorrect Website URLs

    The most common cause of this error is an incorrect URL path to the resource. Even a small typographical error in the file path can prevent the browser from loading the resource.

    Incorrect Server Configuration 

      Sometimes, the server your WordPress website is hosted on might have misconfigured that can fail to load resources properly. This could be due to issues with file permissions, server  protocols, or mod_security settings.

      Plugin or Theme Conflict 

        Conflicts between plugins and themes also can lead to resource error. A poorly coded plugin or a theme may interfere with properly loading resources, resulting in an error message.

        HTTPS/SSL Configuration

          If your website has migrated to HTTPS recently, but the resource URLs are still using HTTP instead of HTTPS, modern browsers may block the resource from loading due to security concerns.

          Caching Issue

            Over-active caching plugins or server-side caching can store incorrect versions of resources, which can cause resource loading problems.

            Network Issues

              Sometimes, Network problems like slow connections or server downtime, can prevent resources from loading in your browser.

                    4. Clear Your Cache

                      Sometimes, the failed resource issue can be caused due to issues with cached files. For example, outdated files stored in a user’s browser cache can sometimes lead to this type of error. These cached files might be older versions of website resources.

                      For potentially resolving the loading issue, clear the browser’s cache and ensure the browser downloads the latest versions of the resources. 

                      Sometimes, issues with your website’s cache could also contribute to the error. If you’re using a caching plugin, there’s a slight chance that it might be serving outdated cached versions of resources.To resolve this, clear your website’s cache.

                      5. Switch to Updated Theme or Plugin

                        In some cases, experiencing this error may occur due to outdated versions  or incompatible themes or Plugins.Then It is best to look for an updated theme.

                        • Go to the “file manager”.
                        • Change the theme name.
                        • Go to the WordPress directory > wp-content/themes folder.
                        • Search for the theme name, and replace the folder’s title.

                        Try to load the website’s page once again to see if it resolves the issue.

                        6. Disable Ad blockers, SSL, and Firewall

                          Sometimes, resource loading issues do not occur due to a fault with the server or website, but a problem with the browser. Adblockers can trigger the error. Try to disable these add-ons from your browser, or disable them all together.

                          Antivirus software or similar plugins block suspicious pages or those with insufficient security. If you are using these types of plugins, try disabling them to see if it makes a difference.

                          7. Check Your File and Folder Permissions

                            First, You need to ensure that the failed resource actually exists. If the missing resource is an image in one of your WordPress website blog posts or page, find it in the media library. If you can see it in the media library, then try to add it again by editing the post or page. If you can’t find the file in the media library, then upload it again.

                            Sometimes, you see broken images or empty boxes in the media library instead of images. Files are unable to be loaded correctly because the file or directory permissions are incorrect. In that case, you may need to fix the error by correcting file permissions. In this case, you have to change them yourself using an FTP client or your hosting provider’s cPanel.

                            8. Replace the Missing Resource

                              This is a common solution of this error, before making any change on the pages, ensure that the “Failed to Load Resource” error exists. When this error occurs, most of the time something is missing from the website.

                              If you’ve recently added a new file or media, replace them to see if the web page works again. If it’s media, then it’s easier to do. There could be other resources that are missing. But according to user comments, it is usually the media that causes the issue.

                              If the media failed to upload or is already deleted, then the “Failed to Load Resource” error appears on the page.Here’s how to fix a issue with media files:

                              • Go to the WordPress Dashboard > Media > Library.
                              • A list of resource files like images will appear.
                              • Now look for the corrupted files. These are the files without any thumbnail.
                              • Replace those corrupted files with a new media file.

                              After following these steps, the error should be removed from the screen. For those who don’t want to go through the hassle of this step, go directly to the file manager

                              • Make sure to name the new file the same as the previous one.
                              • Upload it from the file manager.

                              This replaces the original file with a new, error-free file. The media should now perform well on the page.

                              9. Enable Debugging Mode

                                Enabling WordPress debugging mode can provide more detailed information to fix the exact cause.Debugging mode creates logs that record errors and warnings encountered by WordPress while your site runs.

                                By reviewing these logs, you can find specific issues with plugins, themes, or core WordPress functions that are causing the resource loading problem. However, it’s important to note that analyzing debug logs often requires some technical knowledge of WordPress and PHP.
