In this screencast I show you how to create your own custom 404.php template file using either Dynamik Website Builder, Genesis Extender, Extender Pro, Themer Pro, or Instant IDE. The basic idea is to create a 404.php inside the root of your active Child Theme and customize it however you prefer.

In Genesis, I just copy/pasted the contents of the Genesis 404.php file into my custom one and then tweaked it from there. But how I accomplish this using the various Cobalt Apps DEV tools listed above varies quite a bit as you'll see in the screencast below.
