How To Fix the 404 Not Found Error

1. Retry the web page by pressing F5, clicking the refresh/reload button, or trying the URL from the address bar again.
   
   The 404 Not Found error might appear for several reasons even though no real issue exists, so sometimes a simple refresh will often load the page you were looking for.
2. 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.
3. Move up one directory level at a time in the URL until you find something.
   
   For example, if www.web.com/a/b/c.htm gave you the 404 Not Found error, move up to www.web.com/a/b/. If you get nothing here (or an error), move up towww.web.com/a/. This should lead you toward what you're looking for or at least confirm that it's no longer available.

The Error 404 "Page not found" is the error page displayed whenever someone asks for a page that's simply not available on your site. The reason for this is that there may be a link on your site that was wrong or the page might have been recently removed from the site. As there is no web page to display, the web server sends a page that simply says "404 Page not found".The 404 error message is an HTTP (Hypertext Transfer Protocol) standard status code. This "Not Found" response code indicates that although the client could communicate to the server, the server could not find what was requested or it was configured not to fulfill the request.
The 404 "Not Found" error is not the same as the "Server Not Found" error which you see whenever a connection to the destination server could not be established at all.

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.

The 404 or Not Found error message is a HTTP standard response code indicating that the client was able to communicate with the server, but the server could not find what was requested.

The web site hosting server will typically generate "404 - Not Found" web page, when users attempts to follow a broken or dead link, hence the 404 error is one of the most recognizable errors users can find on the web.

A 404 error should not be confused with "server not found" or similar errors, in which a connection to the destination server could not be made at all. A 404 error indicates that the requested resource may be available again in the future; however, the fact does not guarantee the same content.

404 Not Found Error Emails The 404 not found error notice is something webmasters hate. But the fact is broken HTML and image links do occur. Here is how to get real-time email notices when they do occur.
Yes, I know log files give details of errors. But how often do you check your log files? Unless you examine them every day, it could be weeks even months before you discover the 404 not found errors. By then hundreds, even thousands of visitors may have left your site never to return, nevermind the lost advertising revenue or sales, because they ended up on a 404 not found error page.
196 404 Not Found Error Messages
Recently I encountered this problem when I made some changes to an existing website. I set up a 404 not found error email notification system, and immediately my mailbox was flooded with reports of broken links, search engine bots trying to crawl old nonexistent files, broken image links and missing favicon images.
I was shocked just how many error messages I received - 196 404 not found error messages in 24 hours. It even caught an issue with one of my affiliate campaigns. If I didn't catch that, my AdWords campaign would have sent traffic to a non-existent URL. It could have ended up costing me thousands of dollars in wasted advertising and lost sales.
How to Set Up Your Own 404 Not Found Error Email System
If you want to take a proactive approach and get real-time notices of 404 not found error messages as they happen, then you should set up your own real-time 404 not found error email notification system.
Here's how I did it: By the way, your server must have PHP enabled otherwise this method doesn't work. Ask your server administrator whether your server is PHP enabled and if it isn't, then ask them to enable it.
Also remember to backup any files you intend to edit. If something goes wrong, you can always revert back to the previous file.
The system uses two files; the .htaccess file which tells the server where to send users when there is an error, and the 404 not found error file which sends the 404 not found error email notices to you.



HAVE NICE DAY!!!!!!!!!
