Cannot use Network Admin (Dashboard) on Multi-site after 301 www redirect

I have recently added the 301 redirect non-WWW to WWW on .htaccess for my current running blog multisite (WordPress blog resides under “mysite.com/home/” directory), they seem to work fine after all the changes in those 3 files below:

.HTACCESS

# Redirect Non-WWW to WWW
RewriteEngine on
RewriteCond %{HTTP_HOST} ^mysite.comhome
RewriteRule ^(.*)$ http://www.mysite.com/home/$1 [R=301,L]
# END Redirect Non-WWW to WWW

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

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [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).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*.php)$ $1 [L]
RewriteRule . index.php [L]

WP-CONFIG.PHP

Change From

define('DOMAIN_CURRENT_SITE', 'mysite.com');

Change To

define('DOMAIN_CURRENT_SITE', 'www.mysite.com');

FUNCTIONS.PHP (OF THE MAIN THEME)

Change From

update_option('siteurl','http://mysite.com/home');
update_option('home','http://mysite.com/home');
global $oswcPostTypes;

Change To

update_option('siteurl','http://www.mysite.com/home');
update_option('home','http://www.mysite.com/home');
global $oswcPostTypes;

I could be able to view my sites as usual and log-in to each Site Dashboard BUT CANNOT BE ABLE TO USE the network tab: My Sites > Network Admin > Dashboard, Sites, Users. Is there anywhere else needed to change in order to be able to use the network tab on multisite without using any plugin or changes all the data in the database?
