I recently installed and everything was successful. I can login to the admin site and create posts, categories, users, etc. However when attempting to view the default site (/index.php) I get a Page Not Displayed Error. Firefox says the page isn't redirecting properly. I don't believe it's an issue with the absolute paths as everything is intalled in the root directory of the web server.
/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
define('ABSPATH', dirname(__FILE__) . '/');
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');
