License Keys and WordPress Multisite

This guide explains how PublishPress license keys work for multisite networks, and sites installed on subdomains or subfolders.

License keys on multisite networks

A single site license is all you need to use PublishPress plugins on a WordPress multisite network.

A WordPress multi-site network only has a single plugins directory, which is shared by all sites. So if a plugin is updated for one site, it is updated for all sites. For that reason, a single license can be used for an entire network.

However, the sub-site which activated the license will be the only site that can check for new updates.

We recommend making a single site that controls and activates all licenses to prevent things getting unorganized.

License keys for different sites installed on the same domain

PublishPress support and plugin updates are provided using site licenses. That is not the same as a “domain license”. So if you have separate WordPress installs located across subfolders and subdomains, each site will require a unique site license.

One way to think about this is that you need a license for each /wp-content/plugins/ folder. A multisite network only has one of these folders, but separate WordPress installs all have their own version of this folder.
