Is index.php file is required in child theme?


I am getting below error ,

Broken Themes

The following themes are installed but incomplete.

Name Description

Allegiant Template is missing. Standalone themes need to have a index.php template file. Child themes need to have a Template header in the style.css stylesheet.

Do I need to put index.php file into child theme from parent theme.

Regards , Saikat

Hi Saikat,

Actually, there's only two files required in child theme: the style.css and the functions.php.

I simply think that your style.css is missing the header. Here's an example of the mandatory header of a child theme.

 Theme Name:   Twenty Fifteen Child
 Theme URI:    http://example.com/twenty-fifteen-child/
 Description:  Twenty Fifteen Child Theme
 Author:       John Doe
 Author URI:   http://example.com
 Template:     twentyfifteen
 Version:      1.0.0
 License:      GNU General Public License v2 or later
 License URI:  http://www.gnu.org/licenses/gpl-2.0.html
 Tags:         light, dark, two-columns, right-sidebar, responsive-layout, accessibility-ready
 Text Domain:  twenty-fifteen-child

Also, you need to enqueue the parent style sheet by including this in your child theme function.php:

add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
    wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );


I second the last answer. However, I found that index.php truly was required for the admin panel to stop complaining that the theme was broken. So, I kept an empty index.php file in there and life was good.
