How to Remove WordPress Dashboard Widgets Print

All you have to do is simply paste the following code in your theme’s functions.php file. Although it maybe a good idea to save this file as a plugin and make it a drop-in plugin.

function remove_dashboard_widgets() {
	global $wp_meta_boxes;

	unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_quick_press']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_incoming_links']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_right_now']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_plugins']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_recent_drafts']);
	unset($wp_meta_boxes['dashboard']['normal']['core']['dashboard_recent_comments']);
	unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_primary']);
	unset($wp_meta_boxes['dashboard']['side']['core']['dashboard_secondary']);

}

add_action('wp_dashboard_setup', 'remove_dashboard_widgets' );
