Please help

I am having problems setting up multisite on Host Gator

I have added the code to wp-config.php

/* Multisite */
define( ‘WP_ALLOW_MULTISITE’, true );
define(‘MULTISITE’, true);
define(‘SUBDOMAIN_INSTALL’, true);
define(‘DOMAIN_CURRENT_SITE’, ‘server-com.tk’);
define(‘PATH_CURRENT_SITE’, ‘/’);
define(‘SITE_ID_CURRENT_SITE’, 1);
define(‘BLOG_ID_CURRENT_SITE’, 1);
define( ‘NOBLOGREDIRECT’, ‘http://server-com.tk’ );

/* That’s all, stop editing! Happy blogging. */

I have this code in my htaccess file
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ – [L]

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ – [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

Also I created a wildcard subdomain that points to document root/public_html/

I am able to create sites in my WordPress dashboard but not able to see them live on the web http://test.server-com.tk/ I get error “This site can’t be reached”
