A 404 error is an HTTP status code that indicates the server cannot find the requested resource. This can be caused by a number of factors, including:

  • Non-existent page or file.

    This is the most common cause of a 404 error. It can happen if you type in a URL incorrectly, or if a page or file has been moved or deleted.

Moved or deleted page or file.

A 404 error can also occur if a page or file has been moved or deleted. This can happen if a website is redesigned or if a file is accidentally deleted.

  • Website redesign: When a website is redesigned, the URLs of the pages on the website may change. This can cause 404 errors if you have bookmarked old URLs or if you link to the website from other websites.
  • Accidental file deletion: If a file is accidentally deleted from a website, it can also cause a 404 error. This can happen if a website owner is updating the website and accidentally deletes a file, or if a hacker gains access to the website and deletes files.
  • Incorrect redirects: If a page or file has been moved to a new location on the website, a redirect should be put in place to automatically forward visitors to the new location. However, if the redirect is not set up correctly, it can cause a 404 error.
  • Outdated links: If you have a link to a page or file that has been moved or deleted, you will receive a 404 error when you click on the link. This can happen if you have bookmarked an old URL or if you link to a website from another website and the URL has changed.

If you encounter a 404 error because a page or file has been moved or deleted, you can try the following:

  • Check the website's homepage to see if there is a notice about the website redesign or the moved or deleted file.
  • Try searching for the page or file on the website using the website's search function.
  • Contact the website owner and ask them for the new URL of the page or file.

If you have tried all of these steps and you are still unable to find the page or file, you may need to contact the website owner or your internet service provider for assistance.

Website configuration issues.

A 404 error can also be caused by website configuration issues. This can happen if the website is not configured correctly, or if a file is not properly linked to the website.

  • Incorrect .htaccess file: The .htaccess file is a configuration file that can be used to control how a website works. If the .htaccess file is not configured correctly, it can cause 404 errors.
  • Incorrectly linked files: If a file is not properly linked to the website, it can cause a 404 error. This can happen if the file is not in the correct directory, or if the link to the file is incorrect.
  • Missing or incorrect redirects: If a page or file has been moved to a new location on the website, a redirect should be put in place to automatically forward visitors to the new location. However, if the redirect is not set up correctly, or if it is missing, it can cause a 404 error.
  • Incorrect DNS settings: The DNS settings for a website control how the website's domain name is translated into an IP address. If the DNS settings are incorrect, it can cause 404 errors.

If you encounter a 404 error because of a website configuration issue, you can try the following:

  • Contact the website owner and ask them to check the website's configuration.
  • Try accessing the website from a different browser or device.
  • Clear your browser's cache and cookies.

If you have tried all of these steps and you are still getting a 404 error, you may need to contact the website owner or your internet service provider for assistance.
