|Error 404 - File not Found.
The requested url/filename could not be located on this server.
This is a very annoying message that is not appealing nor helping your visitor, and when visitors don't like what they see they leave...
This is what you can do to improve it... make your own Error 404 page and provide useful help for the visitor to carry on navigating through your site.
Now this is how to replace your error file with the default one.
On your sever in the web site root folder there is a file ".htaccess", all you need to do is to add the following line to the file.
ErrorDocument 404 http://www.domainname.com/filename.html
Replace the path of the filename.html with the path to your own error 404 file.
This is a tutorial to put your custom page instead of the error page
