The theme included the licensing plugin: WPBakery Page Builder, we purchased it from wpbakery.com and included it for free in the theme package without any issues. However, if you want automatic updates and support from the plugin developer, you need to purchase it separately (this is 100% optional). Because we are not allowed to include the license key for it, so you do NOT have a purchase code for that plugin and you can’t enter anything in this field. If there is any update, we are accountable for updating the theme with the newest version of this plugin.
