Every time you activate a plugin using a license, the URL for that site is logged on your WPforChurch account licence manager. You can use each plugin on a maximum of websites (based on your purchase tier–the base tier is three websites).
If you have already maxed out your licence activations you can reassign your licenses by deactivating a license for a site you no longer use. Once you have deactivated a site you will have an extra license activation available.
To deactive a licence click on the Payment History tab from the account dashboard and then click on View Licenses next to the appropriate purchase. The resulting screen will list the products in that purchase and how many licenses have been activated.
Let’s say you wanted to deactivate the one site that is using the Church Pack Pro plugin. If you click on the link to Manage Sites for that product the following screen will load and show you the URL for that one site. Simply click Deactivate Site next to the URL and that license will be free to use on another site.
