If you have clicked a button in your theme's admin panel to visit the theme author's website, you may be prompted to enter your Envato purchase code to access resources. The author's portal is aimed at standalone purchases of the product so will not allow you access based on your Envato Hosted subscription. This is normal!
As part of the Envato Hosted service, your theme license is rolled into your active subscription and used to manage your account and downloads on Themeforest. However, this is not a purchase code. All theme and server support is offered by our trained staff of WordPress veterans in the interest of offering you the best experience possible.
Please see the following for more detail on our support policy and options:
Your theme may come with bundled plugins such as WP Bakery Page Builder or Revolution Slider which ask you to register or purchase. This is not required. Your theme includes a bulk license to use the product and takes on all responsibility for bundling and providing plugin updates along with the theme updates going forward.
