Many of our customers asked questions about activation code for plugins. But you should know, you don’t need any code to activate the plugins. As an author, we have purchased the extended version of plugins and provide them to our customers in our theme’s package. Hence, you don’t need to purchase them yourself or activate them by purchase code.
Only install them through the following path:
Dashboard > Appearance > Install Plugins
