How to Fix ‘Failed to Load Response Data’ In WordPress

WordPress is a great platform for blogging and website building. One of the many features that make WordPress such a popular choice is its ability to add content from other websites, like YouTube or Flickr.

As long as you have permission to use the content, it’s easy to create posts with embedded media. But what if something goes wrong? What if you get an error message while trying to embed video or audio files in your post?

Here are some tips on how to fix failed to load data in WordPress:

What Is Failed To Load Resource Error?

Failed to load resource error is encountered when you try to create a post with embedded media that is blocked by the host of that website.

For instance, this error can occur when you try to post a YouTube video and the site administrator has set a security option that prevents embedded content from other websites.

In this instance, the embedded video player will show a message with an error code ‘failed to load resource’.

Since media files are often hosted on external servers, they have to be accessed via your website server. If the site administrator has set security settings that prevent requests to external servers, then posts with embedded media will not be allowed.

How To Fix Failed to load Data In WordPress?

There are several options you can try before giving up on using embedded media in your post:

1) Deactivate security plugins:

If you face a problem ‘failed to load resource’ with error 400 status, the server responded with an HTTP status code 400 which means “Bad Request”. The other error codes are 401,403.

In this case, if you have installed a security plugin on your website, then this might be the reason for blocked media files. Try disabling or uninstalling any such plugin and see if this helps.

2) Disable & reactivate all plugins:

Deactivate all plugins

Many times, third-party plugins which you have installed on your WordPress blog can interfere with the media files and cause this error.

Some of these plugins are known to cause this type of error, so try disabling all the plugins and see if it fixes the issue for you.

3) Update theme and plugins:

WordPress failed to load response data errors that might be caused by outdated themes and plugins. So, it makes sense to update all your WordPress themes, plugins, and core files to the latest version and see if this fixes the issue for you.

4) Change the default WordPress URL:

In my research, the topic of ‘failed to load response data‘ with status 400 came up a lot of times. Changing the default URL of the WordPress site is one of the best solutions to fix the 400/404 not found issue.

Sometimes you may get failed to load response data in WordPress due to HTTP or HTTPS protocols, which means your site is accessible via a secure or non-secure connection.

If you change the URL from HTTPS to HTTP or vice versa, then WordPress will fix the 400/404 or fail to load response data issue.

To change the default URL of the WordPress website, login to your WordPress and go to the Setting> General section.

Change website URL

Note: Don’t forget to backup your entire site before making any significant changes, and if you’re not sure what to do, then it’s probably best to leave this option alone.

5) Reinstall WordPress:

If you find no other solution that works, then the only option left is to reinstall WordPress on your site. For the best results, you should also delete the old database tables and start fresh with a new database.

It’s always a good idea to back up your site before deleting the database, but if you’re not sure how to do that, then you should hire a WordPress developer to assist you.

If none of these fixes work for you, then the only thing left is to re-upload or re-install WordPress on your website.

6) Request a review on the concerned website:

In some cases, WordPress fails to load data from external servers due to the network configuration or server issue. So, if you are sure that this isn’t an issue with your website, then it’s best to contact the concerned website to look into this issue.

If your site is hosted with a shared hosting company, then contact them to request a review on the website to find the root cause of this issue.

You can also contact the hosting company on which the concerned website is hosted, so they can look into this issue and notify you of the possible causes of the ‘failed to load response data’ error.

It’s worth mentioning here that WordPress has got a dedicated support channel, where you can discuss the issues with WordPress experts and relay detailed information about your problem.

7) Test with a different browser:

Test different browser

If none of the abovementioned options work, then it’s probably best to use another web browser instead of using your regular browser.

For example, if you’ve tested the website and found no issues with Google Chrome, but the website loaded error ‘failed to load response data’ on Firefox browser, then try another web browser like Internet Explorer or Safari.

You can use the Google Chrome browser incognito mode to check for this problem. Most of the time, you’ll find that the issue is with your web browser itself.

If all else fails, try deleting the cached data in your web browser and see if that fixes the problem.

Summary

There are several reasons why WordPress fails to load response data. It can be anything from outdated themes or plugins, incorrect configuration, or server issues.

If your site is hosted with a shared hosting company, the best thing to do is consult with your hosting support and ask for assistance.
