Hostinger WordPress Multisite Setup Guide 2026 –
Complete Step-by-Step

What is WordPress Multisite?

WordPress Multisite is a feature that allows you to run a network of websites from a single WordPress installation. All sites share the same WordPress core files, themes, and plugins — managed from one dashboard. Perfect for web agencies managing multiple client sites, businesses with multiple brands, or educational networks.

Step 1 – Enable WordPress Multisite

1. hPanel → File Manager → public_html → wp-config.php
2. Click Edit
