Seeing a “failed to load resource” error on a website’s interface or browser’s inspect tool is not unusual. Other users experience the same problem.

But the good thing is that this problem has a solution.

This article will show proven methods to solve this error. Despite the challenge of addressing this problem, it is possible to find the way out.

The “failed to load resource” error is often due to compatibility issues or HTTPS URL issues.

But sometimes, these common causes aren’t the real problem. Some issues need different approaches to see how to fix them.

The following shows the possible causes and the ways to resolve them.

The Potential Causes of Failed to Load Resource Error


Something Interferes with The Requests to Communicate with The Server’s Resources

WordPress users know that themes, plugins, and WordPress systems run on PHP scripts. These PHP scripts are responsible for sending requests to communicate with the server’s resources.

Now, this is where the problem occurs. When something hinders these requests, the WordPress platform has difficulty fetching the resources.

That’s when the text “Failed to Load Resource” appears. To get a better idea of how this error occurs, it helps to see how WordPress generates a page.

It includes various folders and files, like stylesheets, scripts, and images. When the pages load, the files also load via the user’s browser.

However, there are times when the browser has an issue loading the files. In this case, the “failed to load resource” error will show up again.

In this instance, it will add a notice in the error console to help users solve or debug the problem.

Each error can be different, depending on the types of resources used on the website. These could be CSS stylesheet, Javascript, or an image.

Thankfully, the errors come with helpful messages next to them.

A Few Examples of The “Failed to Load Resource” Errors

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

Despite having this error on one page of the website, the rest of the pages will work fine. However, bugs and loading issues are frustrating for visitors and can lead to less traffic.

The next part of this article will explain how to fix the “Failed to Load Resource” errors.

How to Fix the “Failed to Load Resource” Errors in WordPress

Note that it is vital to backup files before taking any action to fix the “Failed to Load Resource” errors. So, before doing anything, back up your files first.

Some of the issues occur because of incompatible plugins, URL configuration issues, or outdated plugins or themes.

Use these methods to solve the problem:

Edit the WordPress URL


One lesser-known cause of the error is a problem with the WordPress URL. Fixing the URL from the settings can make a difference.

Here’s how to do it:

  • Go to the Settings > General Page
  • Search for the WordPress Address and Site Address options
  • Ensure that the URL from the Site Address options and WordPress Address are correct. Check if the URL has a “www” or not. A “www” and “non-www” URL are two different addresses. When enabling the SSL in the website, the URL should be HTTPS instead of HTTP.
  • Click “Save” to store the settings.
  • Visit your website to see if the error is now gone.

Important Note: Before changing anything, it is essential to take advice from a professional, a WordPress expert, or a web host technical support team.

Changing the URL without knowing how to do it can make the website inaccessible. It is crucial to configure it the right way to avoid any problem in the future.

This solution would be the last resort when other solutions do not work.

Look for Another Theme

Experiencing an error can indicate a problem with an incompatible or outdated theme. If that is the case, it’s best to look for a compatible theme.

Or switch back to the default theme. After changing the theme, reload the page to see if the changes are successful.

Doing this is easy with admin access. However, if the user doesn’t have access to the admin section, the following steps may help:

  • Go to the file manager.
  • Change the theme’s name.
  • Go to the WordPress directory > wp-content/themes folder.
  • Search for the theme name, and replace the folder’s title.
  • Load the website’s page once again to see if it resolves the issue.

Disable and Reactivate All the Plugins


Disabling and reactivating all the plugins is the easiest and most accessible solution

If the problem still occurs, check for any errors in the plugins, and fix them accordingly. By disabling and reactivating all the plugins users can find the real cause of the issue.

Disable Adblockers, SSL, and Firewall


Sometimes, it is not a fault with the server or website that causes the error, but a problem with the browser.

Adblockers can trigger this error. Try to disable these add-ons from your browser, or disable them altogether.

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

Replace the Missing Resource

This is a common solution among developers and WordPress experts. 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, one idea is to replace them to see if the web page works again. If it’s media, then it’s easier to do.

Of course, 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 problem with media files:

  • Go to the WordPress Dashboard > Media > Library.
  • A list of images will appear.
  • Look for the corrupted files or media. These are the files without any thumbnail.
  • Replace those corrupted files or media with new ones.
  • Upload the new file.

Completing these steps should remove the error 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. Then, upload it from the file manager.

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