Sorry, I was trying to say I think it not is possible to solve the problem you described.

You are welcome,

It appears you have only changed a comment.
Let’s start over:
First you should make a child theme
Then in the child functions.php you could could have something like this:

/**
 * Register more widget areas.
 */
function more_twentythirteen_widgets_init() {
	register_sidebar( array(
		'name'          => __( 'Extra Widget Area', 'twentythirteen' ),
		'id'            => 'sidebar-3',
		'description'   => __( 'Appears blah-blah-blah', 'twentythirteen' ),
		'before_widget' => '<aside id="%1$s" class="widget %2$s">',
		'after_widget'  => '</aside>',
		'before_title'  => '<h3 class="widget-title">',
		'after_title'   => '</h3>',
	) );
	register_sidebar( array(
}
add_action( 'widgets_init', 'more_twentythirteen_widgets_init' );

Then you could create a new file in the child theme with the name sidebar-extra.php
And with the following content:

<?php
/**
 * The sidebar containing the "extra" widget area
 *
 * Displays bLAHBLAH.
 *
 * If no active widgets are in this sidebar, hide it completely.
 *
 * @package WordPress
 * @subpackage Twenty_Thirteen
 * @since Twenty Thirteen 1.0
 */

if ( is_active_sidebar( 'sidebar-3' ) ) : ?>
	<div id="quaternary" class="sidebar-container" role="complementary">
		<div class="sidebar-inner">
			<div class="widget-area">
				<?php dynamic_sidebar( 'sidebar-3' ); ?>
			</div><!-- .widget-area -->
		</div><!-- .sidebar-inner -->
	</div><!-- #quaternary -->
<?php endif; ?>

Then you could put this in the child functions.php

/**
 * Whenever the sidebar is called, also call the extra sidebar
 */
function get_extra_sidebar() {
	get_sidebar('extra');
}
add_action( 'get_sidebar', 'get_extra_sidebar' );

Instead of file index.php, shouldn’t the virtual directory go to root directory ( / ) ?

Mike, you’ll have better results if you start your own topic, this one is ‘resolved’.

Or just try the manual update referred above ;|

Here are the codex default args from http://codex.wordpress.org/Function_Reference/register_post_type
Probably a good place to start…

add_action( 'init', 'codex_book_init' );
/**
 * Register a book post type.
 *
 * @link http://codex.wordpress.org/Function_Reference/register_post_type
 */
function codex_book_init() {
	$labels = array(
		'name'               => _x( 'Books', 'post type general name', 'your-plugin-textdomain' ),
		'singular_name'      => _x( 'Book', 'post type singular name', 'your-plugin-textdomain' ),
		'menu_name'          => _x( 'Books', 'admin menu', 'your-plugin-textdomain' ),
		'name_admin_bar'     => _x( 'Book', 'add new on admin bar', 'your-plugin-textdomain' ),
		'add_new'            => _x( 'Add New', 'book', 'your-plugin-textdomain' ),
		'add_new_item'       => __( 'Add New Book', 'your-plugin-textdomain' ),
		'new_item'           => __( 'New Book', 'your-plugin-textdomain' ),
		'edit_item'          => __( 'Edit Book', 'your-plugin-textdomain' ),
		'view_item'          => __( 'View Book', 'your-plugin-textdomain' ),
		'all_items'          => __( 'All Books', 'your-plugin-textdomain' ),
		'search_items'       => __( 'Search Books', 'your-plugin-textdomain' ),
		'parent_item_colon'  => __( 'Parent Books:', 'your-plugin-textdomain' ),
		'not_found'          => __( 'No books found.', 'your-plugin-textdomain' ),
		'not_found_in_trash' => __( 'No books found in Trash.', 'your-plugin-textdomain' )
	);

	$args = array(
		'labels'             => $labels,
		'public'             => true,
		'publicly_queryable' => true,
		'show_ui'            => true,
		'show_in_menu'       => true,
		'query_var'          => true,
		'rewrite'            => array( 'slug' => 'book' ),
		'capability_type'    => 'post',
		'has_archive'        => true,
		'hierarchical'       => false,
		'menu_position'      => null,
		'supports'           => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
	);

	register_post_type( 'book', $args );
}

Greetings

I wouldn’t try to back it up and then restore later. It would be easier to enable the WordPress maintenance mode, either via a plugin or manually create the hidden .maintenance file.

Even easier, you can just rename the index.php file. And name it back when you want to go live again.

Good Luck
