Problem editing Prose functions.php

[jfsebastian]

I think I got myself in trouble. I was trying to setup a custom header in my Prose theme according to http://www.studiopress.com/tutorials...-custom-header. After I made the changes via the Edit Themes function in Wordpress I updated the file. It's not saving properly. The admin panel returns to a blank screen. My page at www.prepareandprosper.net will not load either. How do I undo this? The code looks like:

<?php
/*
WARNING: DO NOT edit this file under any circumstances.

*/

/**
* This file calls the init.php file for both Genesis and Prose.
*
* It initializes the Genesis framework, and loads the Prose library as well.
*
* This file is a core Prose file and should not be edited.
