404 pages display when someone tries to access a page on your website that doesn't exist.
Our hosting accounts allow you to use your home page as your 404 page, or you can create a custom one.
Server-side scripts, such as ASP.NET and PHP, might not work on custom 404 pages because of how Web server software (i.e. IIS and Apache) handles them.
To use a customized 404 error page, you must first upload a custom page to your hosting account, and then enter the URL to your custom page.
Links in the 404 page must be absolute, e.g. http://www.yoursite.com/page.html or else they will break when clicked from the 404 page.
