Author and date of publication on page

Hi there,

Give this a shot:

add_filter( 'generate_entry_meta_post_types', function( $types ) {
    $types[] = 'page';

    return $types;
} );

add_action( 'wp', function() {
    if ( is_page() ) {
        add_action( 'generate_after_entry_header', 'generate_post_meta' );
    }
} );

Let me know :)

Thanks, it works :)

You're welcome :)
