with PHP 4.2, you might also be hitting http://bugs.php.net/bug.php?id=13936
I just encountered this problem. I solved it with:
define(‘ABSPATH’, “/fully/qualified/path/to/install/dir” . dirname(__FILE__));
require_once(ABSPATH.’wp-settings.php’);
DD, that would be ‘/home/wh60319/public_html’ for you.
