Community Q&A

How do I enable WordPress Multisite?

You must define the WP_ALLOW_MULTISITE constant in your wp-config.php file and then follow the network setup instructions in the WordPress dashboard.

Can I use WooCommerce with WordPress Multisite?

Yes, but it requires careful management of plugins and often third-party tools like WooCommerce Multistore to sync products across different sites.

What should I do if my multisite URLs break?

Restore from a database backup immediately. If no backup exists, you may need to manually correct the site and home URLs in the wp_blogs and wp_options tables.
