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.
