WordPress Multisite installation

Upload the plugin on Network Admin plugins page, but don't activate it. It is not allowed to enable "Network Activate" for the plugin on Network plugins page, instead activate it on the plugins page of each sub-site. Also note, that each activation on each sub-site requires separate license.
