What is WordPress Multisite?

WordPress Multisite, formerly known as WordPress Multi-User (WPMU), is a powerful feature that enables every WordPress development agency to manage multiple websites from a single WordPress dashboard efficiently. This functionality is ideal for businesses, organizations, and individuals who need to streamline website management, allowing easy updates and modifications across all sites in the network.

A prime example of a WordPress multisite installation is WordPress.com, which hosts millions of websites. With Multisite, you can establish a main website or network and seamlessly add multiple subsites. In this setup, all sites share the same WordPress installation, database, and set of plugins and themes, effectively transforming a single website into a network of interconnected sites.

Key Features of  WordPress Multisite

WordPress Multisite is an easy-to-use tool that allows you to manage more than one website from one single WordPress installation. Rather than having to install WordPress on each website separately, you can operate an entire collection of websites—a network—from one control panel. Such websites may employ subdomains (in the form of https://john.example.com) or subdirectories (in the form of https://www.example.com/john/). You can even link in fully independent domains to individual sites if necessary.

As the one in charge of operating the network, you’re referred to as the Super Admin. This means that you have complete control over all facets, from user permissions to site settings and creating new sites. A standard site admin, by contrast, is in charge of their own site within the network. While they may manage posts, pages, and everyday content, they’ll have no access to network settings or tools.

One of the biggest benefits to being a Super Admin is being in control of themes and plugins across the entire network. You can install them all at one time, but select which ones to make available for other sites to use. This consolidates security and streamlines maintenance. You can also apply custom themes to multiple sites, which is incredibly handy if you have to support multiple languages, currencies, or branding.

Content is controlled jointly. Content can be viewed by Super Admins on all sites, but individual admins manage what appears on their own. Though they cannot install plugins directly, they have the ability to activate or inactivate ones that have been made available by the Super Admin. Overall, WordPress Multisite is an intelligent way to efficiently operate numerous sites. It streamlines administration, maintains uniform tools and design, and allows for expansion of web presence with less effort.

Who Should And Shouldn’t Use WordPress Multisite?

Although WordPress Multisite is available for central management of multiple sites, it is not for everybody. One main limitation is that all sites in the network use one database, so it’s not easy to back or migrate individual websites separately. Multisite is, therefore, best for situations where all sites have close affinity to one another and the same domain or org.

For instance, a university can use WordPress Multisite to handle dedicated sites for separate departments, faculty blogs, event sites, or student forums under one main university domain. Since all their content, branding, and administrative setup is uniform across the board, handling them in one network makes sense in terms of efficiency and making updates, backups, and user permissions, easy.

Conversely, freelancers or web shops that manage unrelated clients’ sites should not use Multisite. The shared database can become problematic if one client wishes to transfer their site to another platform. Each site would not have the independence necessary for such processes. Standalone WordPress installations in such situations grant more control, flexibility, and reassurance to both clients and developers.

How to Install WordPress Multisite?

Step 1 : Prepare Your WordPress Installation

Before enabling Multisite, ensure your current WordPress setup is ready for network configuration. If this is not a fresh installation, it’s strongly recommended to back up your database and site files, as core changes will be made during the process.

Confirm that Pretty Permalinks are functional. Navigate to Settings > Permalinks and select any structure other than “Plain” to verify that your server’s URL rewriting is working correctly.

Deactivate all active plugins temporarily to avoid conflicts during the network setup. You can reactivate them after the Multisite installation is complete.

Suppose you intend to run WordPress from a subdirectory (rather than the web root). This configuration should be in place before enabling Multisite, as it affects how the network is initialized and accessed.

Step 2: Enable the WordPress Multisite Feature

By default, the WordPress Multisite feature is disabled. To enable it, you need to add a line of code to your site’s wp-config.php file. You can do this by accessing the file through cPanel or by connecting to your site via FTP.

Once you locate the wp-config.php file in your site’s root directory, open it and find the line: “That’s all, stop editing! Happy blogging.” Just above this line, insert the following code:

/* Multisite */
define( 'WP_ALLOW_MULTISITE', true );

After adding the code, save the file and refresh your browser. The WordPress Multisite feature is now enabled.

Step 3: Network Setup

Now, head over to “Tools” Network Setup.” If you get a message that Apache’s mod_rewrite module needs to be installed, don’t worry—most top WordPress hosting providers already have this module enabled by default.

Choose how you want your network’s websites to be structured using subdomains (like site.example.com) or subdirectories (like example.com/site).

Next, enter a title for your network and double-check that the network admin email address is correct.

Once everything looks good, click the “Install” button.

After installation, you’ll see some code that needs to be added to your wp-config.php and .htaccess files. Use an FTP client or your hosting control panel’s file manager to do this. Just copy and paste the code into the appropriate files.

After file setting, it is now time to follow the above instructions to move ahead when setting up things.

Step 4: WordPress Multisite Configure and Network Setting

To configure network settings, go to the dashboard and tap network dashboard. From there add new sites, and other important configurations. Now tap on Network Admin >Dashboard.

Now you will be redirected to the multisite network dashboard. There are new menu items to manage multisite network. You will also come across a Right Now dashboard widget that helps to generate a new site and add new users.

To ensure network setting, click on the settings link present in admin dashboard sidebar followed by network Settings. The first option you will see on network settings page will help to set your network title and admin email address.

How to Enable User Registration on WordPress Multisite?

The Registration Settings section on the Network Settings page is essential for managing user access in your WordPress Multisite network. By default, site and user registrations are disabled. However, you can enable them to allow existing users to create new sites or let new users sign up on your multisite network. This flexibility makes it easier to expand your network while maintaining control over user access.

When enabling registration on your multisite network, you can select the Registration Notification option to receive email alerts whenever a new user or site is registered. Additionally, if you want to allow individual site administrators to add new users to their sites, you can enable the Add New Users option.

The Limited Email Registration feature enables you to restrict site or user registrations to specific email domains. This ensures that only users from designated domains, such as your organization’s, can register and create accounts or sites. Additionally, you have the flexibility to block registrations from certain domains as needed.
