Hi,
Thanks for using our plugins. I can help out here.
Yep you can renew and use it on a different domain.
In fact you could change domains anytime you like.
To do that remove your license keys from your account on TheEventsCalendar.com and then reactivating them on your new domain and that should be it.
To do that, login to your account and go to My Account > License Keys
Click “Disconnect now” next to all the urls and go to your site and add those license keys back.
Let me know how that works out for you.
Thanks
