Sometimes when going from development to production the domain of the site changes and if you’re not going to keep alive development server, it doesn’t make any sense for both the user or us to make the user buy two licenses just for that.
With Term and Category based Posts Widget v4.7 and higher you’ll be able to just deactivate the license on your development site and activate it on production.
To deactivate the license, submit an empty value as the license key and press save.
You can manage your Site Licenses also by using the Dashboard.
