How to install WebinarPress in a Multisite environment
WebinarPress is compatible with a WordPress multisite environment. On the network admin settings, you can install the plugin like normal.
If you 'network activate' Webinapress, then it will be accessible from every subsite. If not, then you have to activate each website separately.
When Webinarpress Pro is installed on a multisite WordPress website, then you only need to insert the license key once on the network admin settings page to receive automatic updates. Automatic updates and support on multisite environments are only available if you have an Agency license.
