i have been using this mod on and off for years.. i can help you but not understanding what you mean by cat_filter did not work.. you get the info in your admin under Tools>>multi-site copy that into your cat-filter. Make sure you name it >>>
https://your_site.com_config.php.
this is one of mine
$template_dir = "kandi"; >>>>>>>>>your template name
define('SITE_NAME','kandi'); site name
define('HTTP_SERVER', 'https://thekandibazaar.com'); your site name
define('HTTPS_SERVER', 'https://thekandibazaar.com'); your site name
define('CATEGORIES_ROOT','0'); //root categories is 1 for this site
define('DIR_WS_CATALOG', '/'); >>>>>>>>>>>>>>>>>>>>> if you point your domain name to html/shop in your cpanel then don't change if this is not the main site. I use shop---some people use cart or some people have their store in the root directory.
define('DIR_WS_HTTPS_CATALOG', '/');
