WordPress Multisite Network Setup

WordPress Multisite network setup

Multisite lets you run several sites on one installation: a shared core, shared plugins and themes, managed from a single panel. It does not suit everyone, and the decision is worth weighing before implementation.

When it is convenient

• several similar sites under one management — branches, regions, brands;
• language versions as separate sites with different structures;
• sites that have to be updated in step with each other;
• internal projects sharing the same plugin set.

What to know in advance

A shared core means shared risk. A plugin update applies to every site in the network. If it breaks something, it breaks everywhere at once.

Not every plugin is compatible. Some extensions are not built for a network: settings leak between sites or get stored in the wrong place.

Splitting a network is hard. Extracting one site from Multisite into its own installation is considerably more difficult than merging them. So the decision should be made with several years in mind.

Hosting. A network of dozens of sites loads the server appreciably more than a single site — that needs factoring into the plan.

What is included

Enabling the network, configuring domains or subdomains, administrator roles and permissions, shared plugins and themes, compatibility checks for existing extensions, and backups that account for the network structure.
