A 404 error is an HTTP status code that indicates that a web server could not find the requested resource or page. When a user tries to access a page on a website that no longer exists or has been moved, the web server will return a 404 error message to the user’s browser.
The term “404 error” comes from the error code that the web server sends back to the browser when it cannot find the requested page. The error code indicates that the page is missing or does not exist, and the browser displays a message such as “404 Page Not Found” to the user.
404 errors can occur for a variety of reasons, such as when a page is deleted or moved, when a user types in the wrong URL, or when a link on a website is broken or outdated. While 404 errors can be frustrating for users, they are a normal part of web browsing and are usually harmless.
Web developers and website owners can customize 404 error pages to provide more helpful information to users, such as links to other pages on the website or a search bar to help users find the content they are looking for. They can also use tools such as Google Search Console to identify and fix 404 errors on their website, improving the user experience and ensuring that search engines can properly index their content.
What are the common causes of 404 errors?
A 404 error is an HTTP response status code that indicates that the server could not find the requested resource, such as a web page or file. The following are some of the most common causes of 404 errors:
Typos or incorrect URLs: One of the most common causes of a 404 error is an incorrect URL or a typo in the URL. If the user enters an incorrect URL or mistypes a URL, the server cannot locate the requested resource and returns a 404 error.
Deleted or moved pages: If a website owner deletes or moves a page without updating internal links or redirects, users attempting to access the original URL will receive a 404 error.
Broken links: If a website has broken links or links to external pages that are no longer available, users who click on those links will receive a 404 error.
Server or network issues: Sometimes, a 404 error may occur due to server or network issues. For example, the server may be down, or there may be connectivity issues preventing the user from accessing the resource.
Access restrictions: If a resource is restricted or requires authentication, users who attempt to access the resource without proper authorization will receive a 404 error.
How do I fix error 404?
Fixing a 404 error will depend on the root cause of the error. Here are some general steps you can take to troubleshoot and fix a 404 error:
Check the URL: Verify that you have typed the correct URL and there are no typos. If you are clicking on a link that is producing a 404 error, check to make sure the link is not broken or outdated.
Clear your browser cache: Clearing your browser cache can sometimes resolve a 404 error, as it will force your browser to download the latest version of the page.
Refresh the page: Sometimes, a 404 error may be temporary, and refreshing the page may resolve the issue.
Search for the page: If you cannot access a specific page, try searching for the page using a search engine or the website’s search function.
Check for broken links: If you are a website owner, use a tool to check for broken links on your website and fix any broken links that are leading to 404 errors.
Create a redirect: If you have moved or deleted a page, create a redirect from the old URL to the new URL to ensure that users are automatically redirected to the new page.
Contact the website owner: If you continue to experience a 404 error on a specific website or page, contact the website owner or administrator to report the issue.

404 Errors can occur due to a variety of reasons, including incorrect URLs, deleted or moved pages, broken links, server or network issues, and access restrictions.
To fix a 404 error, you should verify the URL, clear your browser cache, refresh the page, search for the page, check for broken links, create a redirect, or contact the website owner for assistance.
