add_theme_support( 'custom-header' ) does not add option menu in dashboard

Question

I'm writing a new theme from scratch, based off the Toolbox theme. My installation of WP is straight out of the box. I added add_theme_support('custom-header'); to my functions.php file, but the "header" options screen does not appear in the dashboard. I can see it if I visit the site, in the toolbar at the top, but not in the dashboard. Am I missing something?

Answer 1

From Codex:

If attached to a hook, it must be after_setup_theme. The init hook may be too late for some features.

Try this

if ( ! function_exists( 'mytheme_setup' ) ):
    function mytheme_setup() {
    add_theme_support( 'custom-header' );
    }
endif;
add_action( 'after_setup_theme', 'mytheme_setup' );

If you use Toolbox Theme, find in functions.php

function toolbox_setup() {

and add inside this function

add_theme_support('custom-header');

I was told that add_theme_support('custom-header'); is not supposed to work as I expected yet. See the full answer I received here.
