Multi Site not installing

I’ve installed WordPress on some spare hosting at Heart Internet.
The asks about multi site so have said ok to that and logged in. Tools/Network setup says to add some lines to wp_config

/**
 *  Change this to true to run multiple blogs on this installation.
 *  Then login as admin and go to Tools -> Network
 */

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
	define('ABSPATH', dirname(__FILE__) . '/');

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . 'wp-settings.php');

/* Destination directory for file streaming */
define('WP_TEMP_DIR', ABSPATH . 'wp-content/');

define('WP_ALLOW_MULTISITE', true);
define('MULTISITE', true);
define('SUBDOMAIN_INSTALL', false);
define('DOMAIN_CURRENT_SITE', 'softwaregurus.co.uk');
define('PATH_CURRENT_SITE', '/');
define('SITE_ID_CURRENT_SITE', 1);
define('BLOG_ID_CURRENT_SITE', 1);
/* That's all, stop editing! Happy blogging. */

and to htaccess

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]

I still don’t get any network menus. Just the network setup which tells me a network has been detected.

I’ve asked Heart to look at it as well but a little confused now.
Any ideas please.
Cheers
