Many plugins come with shortcodes to make it easy for users to choose where to output certain bits and bobs. Many Genesis themes come with home pages built entirely of widget areas. Shortcodes do not work in widget areas by default.
You can add this code either to your themes functions.php file, which would make all the widget areas of your site allow shortcodes, or to your themes front-page.php file before the genesis() function at the end to apply this just to your home page.
Once you’ve added this. You can refresh your home page and the shortcode will be working as you’d expect.
