When attempting to upgrade from 2.0.1 (multisite) to 2.3, the upgrade didn't create a multisite lib/support/index.php, so I created one myself ("[path]" is a path to the gallery root dir):
<?php
define('GALLERY_CONFIG_DIR', dirname(dirname(dirname(__FILE__))));
require('[path]/lib/support/index.php');
?>
Is this the correct content (note the three "dirname"s)? It seems to work ...

The syntax did change from 2.01 to 2.3 so you might want to look at the G2.3 code for an example.
