Network not Apearing for Multisite Setup

I am trying to create a Multisite and followed the instructions provided on the config.php file and addeded:

* For developers: WordPress debugging mode.
* Change this to true to enable the display of notices during development.
* It is strongly recommended that plugin and theme developers use WP_DEBUG
* in their development environments.
define('WP_DEBUG', false);

define(‘WP_ALLOW_MULTSITE’, true);

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

Then, uploaded via ftp and nothing "Network" still didn't appear. I also, tried via, C-Panel and still no "Network" under the tools.

Any help would be great.
