Create your own custom error page
This custom error page shows some standard error information and reports the error to the webmaster by e-mail. The script works for dead links and will report expired hot links from other sites (the IP address). Just add bad URL's and IP addresses into a text file to get the errors only once.
Create a .htaccess file in your root and enter these most common error code definitions
Save below code in file "error.php"
