here is my www.moviemem.dejavugallery.com_config.php
<?php
define('SITE_NAME','Movie Memerablia');
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_CATALOG', '/');
$template_dir = "memorablia";
define('CATEGORIES_ROOT','2'); //root categories is 2 for this site
define('HTTP_SERVER', 'http://www.moviemem.dejavugallery.com/galleryStore');
?>
As you can see, it is much like your examples (which I've been using). I still only see my main site when I enter the URL www.dejavugallery.com/galleryStore.
