Custom Post Template Woes

Good morning,

I wonder if you can help. I’m sure I’m being utterly dense, but I can’t get my custom post type to display via a template file. So far I’ve done the following:

Created a custom post type called ‘Agent’ which is functioning well. My code is here:

// Register Agent Post Type
function agent() {

	$labels = array(
		'name'                  => _x( 'Agents', 'Post Type General Name', 'text_domain' ),
		'singular_name'         => _x( 'Agent', 'Post Type Singular Name', 'text_domain' ),
		'menu_name'             => __( 'Agents', 'text_domain' ),
		'name_admin_bar'        => __( 'Agents', 'text_domain' ),
		'archives'              => __( 'Agent Archives', 'text_domain' ),
		'attributes'            => __( 'Agent Attributes', 'text_domain' ),
		'parent_item_colon'     => __( 'Parent Item:', 'text_domain' ),
		'all_items'             => __( 'All Agents', 'text_domain' ),
		'add_new_item'          => __( 'Add New Agent', 'text_domain' ),
		'add_new'               => __( 'Add Agent', 'text_domain' ),
		'new_item'              => __( 'New Agent', 'text_domain' ),
		'edit_item'             => __( 'Edit Agent', 'text_domain' ),
		'update_item'           => __( 'Update Agent', 'text_domain' ),
		'view_item'             => __( 'View Agent', 'text_domain' ),
		'view_items'            => __( 'View Agents', 'text_domain' ),
		'search_items'          => __( 'Search Agents', 'text_domain' ),
		'not_found'             => __( 'Not found', 'text_domain' ),
		'not_found_in_trash'    => __( 'Not found in Trash', 'text_domain' ),
		'featured_image'        => __( 'Featured Image', 'text_domain' ),
		'set_featured_image'    => __( 'Set featured image', 'text_domain' ),
		'remove_featured_image' => __( 'Remove featured image', 'text_domain' ),
		'use_featured_image'    => __( 'Use as featured image', 'text_domain' ),
		'insert_into_item'      => __( 'Insert into item', 'text_domain' ),
		'uploaded_to_this_item' => __( 'Uploaded to this item', 'text_domain' ),
		'items_list'            => __( 'Agents list', 'text_domain' ),
		'items_list_navigation' => __( 'Agents list navigation', 'text_domain' ),
		'filter_items_list'     => __( 'Filter items list', 'text_domain' ),
	);
	$args = array(
		'label'                 => __( 'Agent', 'text_domain' ),
		'description'           => __( 'Agent Post Type', 'text_domain' ),
		'labels'                => $labels,
		'supports'              => array( 'title', 'editor', 'thumbnail', 'post-formats', ),
		'taxonomies'            => false,
		'hierarchical'          => false,
		'public'                => true,
		'show_ui'               => true,
		'show_in_menu'          => true,
		'menu_position'         => 5,
		'show_in_admin_bar'     => false,
		'show_in_nav_menus'     => true,
		'can_export'            => true,
		'has_archive'           => false,		
		'exclude_from_search'   => false,
		'publicly_queryable'    => true,
		'capability_type'       => 'post',

);
	register_post_type( 'agent', $args );

}
add_action( 'init', 'agent', 0 );

add_action( 'init', 'build_agent_taxonomies', 0 );  
function build_agent_taxonomies() {  
    register_taxonomy(  
    'agent_location',  
    'agent',  // The custom post type
    array(  
        'hierarchical' => true,  
        'label' => 'Agent Location',  
        'query_var' => true,  
        'rewrite' => true,
        'show_ui' => true,
        'show_admin_column' => true             
    )  
);  
}

I’ve tried to created a custom template by copying single.php from the Enfold parent theme (I’m using a child theme) and renaming it single-agent.php. I’ve reset permalinks and tired a few times but none of my changes appear to be having any effect.

Any help / slaps around the face would be appreciated!

Regards,

Ash
