Custom Error Pages Error pages can be both annoying and confusing to users. Among the errors seen, the most common is '404: File not Found' which occcurs if the file has been deleted or moved. Standard messages are neither very helpful or pleasing to view and do not help the user find the desired information. The Control Panel provides a facility where you can customize the errors that your users will see instead of the generic server errors. Custom Error Pages can contain a link to the homepage, search box, webmaster contact information, and anything else that will help your users find what they were looking for.
