Hostinger WordPress Multisite: Setup, Pros & Cons for Agencies

WordPress Multisite (also called WordPress Network) allows a single WordPress installation to power multiple websites. All sites share the same WordPress core, plugin files, and database server, but each site has its own posts, pages, themes, and settings. You manage everything from a central Network Admin dashboard.

Two multisite structures: Subdomain network (site1.yourdomain.com, site2.yourdomain.com) or subdirectory network (yourdomain.com/site1, yourdomain.com/site2). Subdomain networks require wildcard DNS; subdirectory networks are simpler to configure on shared hosting.

Step 1: Enable Multisite in wp-config.php
In hPanel File Manager, open /public_html/wp-config.php and add before /* That's all, stop editing! */:

define('WP_ALLOW_MULTISITE', true);

Step 2: Network Setup
In WordPress admin, go to Tools → Network Setup. Choose subdomain or subdirectory. Click Install.

Step 3: Update wp-config.php
WordPress will display code to add to wp-config.php. Copy and paste it below the ABSPATH define.

Step 4: Update .htaccess
Replace your current .htaccess content with the multisite-specific rules WordPress provides. Access .htaccess via hPanel File Manager (enable hidden files view).

Step 5: Log back in
After saving .htaccess, log out and back in. You'll now see Network Admin in the top admin bar.

Subdomain multisite requires wildcard DNS so that new subsites (site1.yourdomain.com, site2.yourdomain.com) resolve automatically.

In hPanel → DNS Zone Editor, add a wildcard A record:

• Type: A
• Name: *.yourdomain.com (or just * in the subdomain field)
• Points to: Your Hostinger server IP (found in hPanel → Hosting → Details)

Allow 15-60 minutes for DNS propagation. Once active, any new subdomain you create in Network Admin will automatically resolve to your server.

From Network Admin (My Sites → Network Admin), you can:

• Add sites: Sites → Add New. Enter site address, title, and admin email.
• Network-activate plugins: Plugins → Network Activate. Makes a plugin available to all sites without individual activation.
• Manage themes: Themes → Network Enable. Only network-enabled themes are available to sub-sites.
• User management: Users can be super admins (access everything) or site admins (access their site only).
• Site settings: Each sub-site has its own Settings where the site admin controls their content.

Pros:

• Manage 50+ client sites from one dashboard
• Update WordPress core once, updates all sites
• Network-activate plugins (buy one license, use across all sites)
• Shared user accounts — one login for all sites
• Lower hosting cost — one plan, many sites

Cons:

• One plugin conflict or hack can affect all sites
• Not all plugins are multisite-compatible
• Harder to move a single site off the network
• Resource usage is cumulative — busy networks need VPS
• Client access requires custom user roles
