# How to activate the Wordpress multisite function?

The Multisite Network functionality is integrated into the WordPress [CMS](https://help.ex2.com/en/article/what-is-a-content-management-system-or-cms-1c48kdh/?bust=1784052067814). You must first [install and configure WordPress](https://help.ex2.com/en/article/how-to-install-wordpress-via-softaculous-in-cpanel-1g09mqm/?bust=1676572216901) as you normally would. Next, you need to enable this multi-site feature.

You can also enable multi-site functionality on an existing WordPress site. Before activating the multi-site option, however, it is strongly recommended to create a full backup of your WordPress site.

To enable the Multisite Network, open the wp-config.php file for editing using an FTP client or the cPanel file manager.

You must add the following code to your wp-config.php file just before the/* line That’s all, stop editing! Happy blogging. */ .

```
/* Multisite */
set ( 'WP_ALLOW_MULTISITE', true );
```

Once you have added the code, save the changes and upload your edited wp-config.php file to the server.

This code enables WordPress’s multi-site functionality. Once this is enabled, you still need to configure the multi-site network.
