Can't override wp_new_user_notification in child theme functions.php

[zero12345678]

I have the following code placed in the functions.php file in my child theme overriding the wp_new_user_notification functions so that is doesn't send an email to new users that are created.

The last wp_mail function is commented out.

The email is still being sent to the new user's email address though.

if ( !function_exists('wp_new_user_notification') ) :

function wp_new_user_notification( $user_id, $notify = 'admin' ) {
	global $wpdb;
	$user = get_userdata( $user_id );

	// The blogname option is escaped with esc_html on the way into the database in sanitize_option
	// we want to reverse this for the plain text arena of emails.
	$blogname = wp_specialchars_decode(get_option('blogname'), ENT_QUOTES);

	$message  = sprintf(__('New user registration on your site %s:'), $blogname) . "\r\n\r\n";
	$message .= sprintf(__('Username: %s'), $user->user_login) . "\r\n\r\n";
	$message .= sprintf(__('E-mail: %s'), $user->user_email) . "\r\n";

	wp_mail(get_option('admin_email'), sprintf(__('[%s] New User Registration'), $blogname), $message);

	if ( 'admin' === $notify || empty( $notify ) ) {
		return;
	}

	// Generate something random for a password reset key.
	$key = wp_generate_password( 20, false );

	/** This action is documented in wp-login.php */
	do_action( 'retrieve_password_key', $user->user_login, $key );

	// Now insert the key, hashed, into the DB.
	if ( empty( $wp_hasher ) ) {
		require_once ABSPATH . WPINC . '/class-phpass.php';
		$wp_hasher = new PasswordHash( 8, true );
	}
	$hashed = time() . ':' . $wp_hasher->HashPassword( $key );
	$wpdb->update( $wpdb->users, array( 'user_activation_key' => $hashed ), array( 'user_login' => $user->user_login ) );

	$message = sprintf(__('Username: %s'), $user->user_login) . "\r\n\r\n";
	$message .= __('To set your password, visit the following address:') . "\r\n\r\n";
	$message .= '<' . network_site_url("wp-login.php?action=rp&key=$key&login=" . rawurlencode($user->user_login), 'login') . ">\r\n\r\n";

	$message .= wp_login_url() . "\r\n";

	// DISABLE EMAIL FROM BEING SENT TO NEW USER'S EMAIL ADDRESS
	//wp_mail($user->user_email, sprintf(__('[%s] Your username and password info'), $blogname), $message);
}
endif;

Hello zero12345678, welcome to our trac.

A ​pluggable function like wp_new_user_notification() can't be overwritten by a theme. You have to define your function in a plugin which is loaded before wp-includes/pluggable.php gets included.
