Number of Domains
For each license (order), the products can be activated on one domain.
By purchasing a template in which there is a plugin, you are able to activate that plugin for a domain as well. For example, If you have purchased a template with a plugin, and you also purchased that plugin separately in another order, then you can activate for two domains.
The activated domains cannot be removed or altered, double check the domain names you entered before activating the products.
