I think you have your config.php wrong – the SUNRISE line should be the very last one before the require_once line – you have it too early on. It should be like this:
….
if ( !defined(‘ABSPATH’) )
define(‘ABSPATH’, dirname(__FILE__) . ‘/’);
define ( ‘SUNRISE’, ‘on’ );
/** Sets up WordPress vars and included files. */
require_once(ABSPATH . ‘wp-settings.php’);
I’m no expert but that should help. Now to get on with trying to work out why mine isn’t working!
