To add After Entry widget area below the content on single Posts, just add the following in Hello! Pro’s functions.php:
//* Add support for after entry widget add_theme_support( 'genesis-after-entry-widget-area' );
This makes available an additional widget area called “After Entry” at Appearance > Widgets or inside the Customizer ready to be populated with your desired widget(s).
The widget(s) placed in this widget area will automatically appear below the content on single Post pages.
