Introduction to 404 Errors
A 404 error, also known as a “File Not Found” error, is an HTTP status code returned by a web server when a user attempts to access a page that does not exist on the server. The error is often seen when a user attempts to access a page or file that has either been moved, deleted, or renamed or if they enter an incorrect URL in the address bar of their web browser.
Although it is an error, a 404 page can benefit a web developer. It can inform users that a page has been moved or deleted or redirect them to the correct page. Additionally, it can provide a helpful way to track down broken links and other problems with the website.
For website owners, a 404 error can hurt their search engine rankings. Search engines place a heavy emphasis on user experience, and a broken link or missing page can lead to a lower order. Therefore, it is essential to ensure that all pages on your website are working correctly and that any broken links are fixed as quickly as possible.
A 404 error page should be designed with the user experience in mind. It should be informative, provide helpful information, and indicate what the user should do next. For example, it could include a search bar, a link to the home page, or a list of related pages. Additionally, it should be visually appealing, consistent design and branding so that users know they are still on the same website.
In conclusion, a 404 error is integral to the user experience and should be handled professionally and helpfully. It should provide the user with the information they need to get back on track and ensure that the website’s search engine rankings remain unaffected.

How to Troubleshoot and Fix 404 Errors
Four hundred four errors can be incredibly frustrating for website owners and users. Not only do they indicate that something needs to be fixed, but they also need to provide a clue as to the problem or how to fix it.
Fortunately, troubleshooting and fixing 404 errors is relatively straightforward. Here’s a step-by-step guide to getting you started:
1. Check the URL:
The first step in troubleshooting a 404 error is to check the URL. Ensure that the URL is spelled correctly and that all parameters are correct. If the URL is valid, the next step is to check the server.
2. Check the Server:
If the URL is correct, the next step is to check the server. If the server is down or not responding, then the 404 error will be displayed. Make sure that the server is up and running before proceeding.
3. Check for Redirects:
Another possible cause of a 404 error is a redirect. The server may be configured to redirect the user to a new page if a page has been moved or deleted. Check to see if any redirects have been put in place, and if so, ensure they are configured correctly.
4. Check the File Path:
If the URL is correct and the server is up and running, then the next step is to check the file path. Make sure that the file exists and that the way is correct. If the file path is incorrect, then the 404 error will be displayed.
5. Check the Permissions:
Finally, check the permissions on the file. Ensure that the user accessing the file has the correct permissions. If the user does not have the proper licenses, then the 404 error will be displayed.
By following these steps, you can troubleshoot and fix 404 errors. Remember to check the URL, server, redirects, file path, and permissions to ensure that the problem is resolved. Good luck!
