WordPress – Child theme ‘Template is missing’ error

Template is missing appears as an error in your WordPress admin section when there’s an issue with your theme stylesheet header (the commented section in your style.css).

In the child theme example below you’ll notice the line ‘Template: twentyfifteen‘.

/*
 Theme Name:   Twenty Fifteen Child
 Theme URI:    http://wordpress.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
*/

The Template line needs to show the directory path of your parent theme. The template for the Twenty Fifteen example (/wp-content/themes/twentyfifteen) would be twentyfifteen.

I hope that helps!
