Nevertheless, I can’t help without the actual theme.

How would I modify labels and taxonomies of an existing CPT defined in the parent from within the child functions.php file? (I am using a premium theme and want to override their default labels.)

I found a few bits on this elsewhere but it just wasn’t clear enough. You always find a way to make these things clear.

Thanks.

add_action( 'init', 'create_my_post_types' );
function create_my_post_types()
{
        register_post_type( 'super_duper',
                array(
                        'labels' => array
                        (
                                'name' => __( 'Super Dupers' ),
                                'singular_name' => __( 'Super Duper' ),
                                'add_new' => __( 'Add New' ),
                                'add_new_item' => __( 'Add New Super Duper' ),
                                'edit' => __( 'Edit' ),
                                'edit_item' => __( 'Edit Super Duper' ),

                                'view' => __( 'View Super Duper' ),
                                'view_item' => __( 'View Super Duper' ),
                                'search_items' => __( 'Search Super Dupers' ),

                                'parent' => __( 'Parent Super Duper' ),

                        ),
                        'public' => true,
                        'show_ui' => true,
                        'publicly_queryable' => true,
                        'exclude_from_search' => false,
                        'rewrite' => array( 'with_front' => true ),
                )
        );
}

Could you just answer to this question, it is very important please :
my theme inserts shortcode generator in blog posts to do many things. I don’t want registered people to use it.
Can I create with Custom Post Type blog posts just like if I didn’t use this theme ?

Thanks
Nino
