According to our license terms, a customer can use the plugin on the live site(s) specified in his package. A personal package holder can activate the plugin only on one live site. So, he can’t reuse the plugin on another site. If a user desperately needs the plugin for his new site, he must upgrade his license or buy a new package.
*** Before using the plugin on the live site(s), a customer can use the plugin on some under construction fields like→
Sub-domain or multisite: If you are using a sub-domain in the same WordPress installation as a WordPress multisite, then you can use the plugin both on the main site and that sub-domain site. If you are using a different installation of WordPress for a sub-domain, then you can’t use a single site license for that sub-domain. In this case, you have to buy a new single-site license for that sub-domain.
