The “Failed To Load Resource” error is one of the most frustrating issues for many WordPress users these days. This error is quite difficult to fix as it can be caused by several different issues like plugin compatibility issues and HTTPS URL issues and many more. In this post, we will look at some of the causes behind this error and provide some possible solutions to fix it.


What is a “Failed To Load Resource” Error?

As we know many WordPress users have been looking for how to solve the “Failed To Load Resource” problem in various ways. Some people have encountered the error in their browser's developer console, some have seen the error in their WordPress admin dashboard, and some others have encountered problems performing tasks such as uploading media files.

As we know, the WordPress system, plugins, and themes run on PHP scripts. This script sends a request to communicate with a resource stored on the server. When something interrupts this request, WordPress fails to fetch its resources. And that will cause the error “Failed To Load Resource” to appear.


How to Fix “Failed To Load Resource 404” Error

There are many different reasons for the “Failed To Load Resource” error to occur. Using outdated plugins or themes, URL configuration issues, and incompatible plugins are some of the most common culprits causing the error. Here are some methods you can try to fix it.


Method 1: Disable Your Antivirus Plugin

If you experience a status 400 error, something like this: “Failed to load resource: the server responded with a status of 400() /wp-admin/admin-ajax.php�. Then usually it means the URL of the resource has been changed or a plugin is preventing WordPress from accessing the specified file. In most cases, an antivirus plugin can prevent WordPress from accessing some files it deems suspicious. If you have an antivirus or firewall plugin installed on your WordPress site, try disabling it first to see if it fixes the problem.


Method 2: Disable And Reactivate All Plugins

This error is also commonly caused by plugin compatibility issues. To see if the error is caused by a plugin or which one needs to be fixed, you can try deactivating all the plugins on your WordPress site. Then re-enable the plugins one by one, each time the page refreshes and see if the error pops up. Make sure you follow this process until you find the error and find the plugin that is causing the error.


Method 3: Update Themes And Plugins

Some WordPress users have complained about the “Failed To Load Resource” error appearing in the Chrome developer console followed by the message “the server responded with a status of 404”. Almost all reported issues are found to be caused by outdated themes or plugins. Updating to the latest version of the plugin usually resolves this error. You can update the plugin and see if there is a new version of your theme available. If not, please report the problem to the developers.


Method 4: Change Default WordPress URL

The cause behind many cases of “Failed To Load Resource” error is very clear. In most cases, the error only appears after installing the SSL certificate and switching the website from HTTP to HTTPS. Switching a website to use SSL usually means that there will be a change in the URL. Sometimes, the WordPress system and plugins may be confused about whether to fetch resources over the old HTTP or the new HTTPS.

For some users, the problem occurs because the URL for the WordPress installation is still using the old HTTP after switching the website to HTTPS. All they have to do to fix this problem is to change the WordPress Address URL.


If your website also has mixed URLs in WordPress settings, go to the General Settings tab in the WordPress dashboard and change the WordPress Address (URL) to HTTPS. Please note that this is a very risky solution. Please seek professional advice from an expert before changing this URL.

Warning: Changing the default WordPress installation URL can make your website completely inaccessible if not configured properly. It is recommended to consult a WordPress expert or your web host's technical support team for assistance.


If Failed To Load Resource error still persists

Since this error comes in many forms, it's difficult to offer a guaranteed solution that works for all scenarios. If the above methods don't help fix the problem, consider contacting your web hosting provider's customer support team or consulting an experienced WordPress developer. But usually, this error can be resolved with methods 1 and 2.
