Enabling the WordPress Network Feature
By default, access to WordPress network settings is disabled to ensure that users don’t set up their network without researching all that the setup entails. Setting up a network is more than configuring options or turning on a feature.
After you edit and configure your Apache files, you need to enable access to the network menu so you can set up the network and allow the creation of multiple sites. Follow these steps:
Locate the wp-config.php file in the root or /public_html directory of your website.
This file is with the main WordPress files.
Open the wp-config.php file for editing in your favorite text editor.
For Windows users, Notepad will do. For Macs, use TextMate.
Find the line that reads define(‘DB_COLLATE’, ‘’);.
Click at the end of that line. Press Enter and a new, blank line is created.
Some FTP clients let you right-click the filename on the server and choose Edit to edit the file within your FTP program, depending on which program you are using.
Type define(‘WP_ALLOW_MULTISITE’, true );.
This line of code tells WordPress that you intend to use the multisite feature; additionally, it activates the Network option under the Tools menu in your WordPress Dashboard.
Save the wp-config.php file and upload it to your website.
When you log in to the Dashboard of WordPress, you see the Network submenu under Tools.
Choosing this menu item will show the Create a Network admin page. You will also see a reminder to deactivate all your plugins before continuing with network setup.
Before you begin your edits, make a copy of your wp-config.php file and keep it in a safe place on your computer.
