Cause of HTTP 400 Errors
A 404 error is an HTTP status code that means that the page you were trying to reach on a website couldn't be found on their server.
Technically, an Error 404 is a client-side error, implying that the error is your mistake, either because you typed the URL in wrong or the page has been moved or removed from the website and you should have known.
No matter the reason for the 404 error, there is plenty you can do to try to get to that page you were after:
How To Fix the 404 Not Found Error
- Retry the web page by clicking the refresh/reload button or trying the URL from the address bar again. The 404 Not Found error has been known to appear on occasion even if there is no real issue so a simple refresh will often load the page you were looking for.
- Check for errors in the URL. Often times the 404 Not Found error appears because the URL was typed wrong or the link that was clicked on points to the wrong URL.
- Move up one directory level at a time in the URL until you find something. For example, if www.w.com/a/b/c.htm gave you the 404 Not Found error, move up to www.w.com/a/b/. If you get nothing here, move up to www.w.com/a/. This should lead you toward what you're looking for or at least confirm that it's no longer available.
- If you move all the way up to the website's main page, try to run a search for the information you're looking for. If a search function isn't available, try finding your information by using links from this page to dig deeper into the site.
- It's also possible that you simply have the wrong URL - entirely. You might be trying to access a webpage that exists as another name.
When you're this lost, the best course of action is to search for the page at a popular search engine, like Google. Chances are you'll find the page you're looking for.
- Finally, if all else fails, you may want to attempt to contact the webmaster for information on where you might locate the page you're looking for. The webmaster of most Internet sites can be reached via email at webmaster@website.com, replacing website.com with the actual website name.
