You have 6 or 12 months of support included when you buy an item on ThemeForest, based on the purchase plan option. If you wish to renew the support period, must follow:
Renew support. Login on your ThemeForest marketplace account to reactivate your support, go to the 'Superhero – Creative eCommerce Multi-Purpose WordPress Theme' page and simply choose one of the item support renew options.
Buy a new license. This is a cost-effective option if you intend to build more websites with Superhero.
