Lots of googling and I fixed the problem. Basically, you need to stop functions.php from assigning the “sidebar” “body_class” to the body element. The only way to do that is to re-write the function. However, since it is better to use child themes, you have to first remove the previous function and then add a new one. The new one should not write “sidebar” if the page is a single post. This code works for me:

/**
 * Remove the default filter.
 */
function remove_twentythirteen_body_classes(){
	remove_filter( 'body_class', 'twentythirteen_body_class' );
}
add_action('init', 'remove_twentythirteen_body_classes');

/**
 * Extend the default WordPress body classes.
 */
function twentythirteen_child_body_class( $classes ) {
	if ( ! is_multi_author() )
		$classes[] = 'single-author';

/**
 * the && ! is_single() at the end of this is the only real change to the function.
 */
	if ( is_active_sidebar( 'sidebar-2' ) && ! is_attachment() && ! is_404() && ! is_single() )
		$classes[] = 'sidebar';

	if ( ! get_option( 'show_avatars' ) )
		$classes[] = 'no-avatars';

	return $classes;
}
add_filter( 'body_class', 'twentythirteen_child_body_class' );

Did you ever solve this problem?

I’d like to do the same thing.

“Can we just ditch that whole display on update feature? Really it isn’t necessary.”

Please. Silly to have to install a second plugin to have to tame the excesses of another plugin.

I have the same issue. I’m using the latest version of Chrome for OS X. The button and alternative link on the “upload new media” page simply don’t do anything.

Has anyone solved this one?

Thanks for figuring this out!
