How to disable hreflang tags output even for the original domain?

[straube]

You may notice that even if you don't set a language for any domain, you still get a default hreflang tag in your page head. To disable this behavior, you can remove the action that adds that tag. To do so, add the following code to your theme's functions.php file:

function remove_multipledomain_hreflang()
{
    if (!class_exists('MultipleDomain')) {
        return;
    }
    $multipleDomain = MultipleDomain::instance();
    remove_action('wp_head', array($multipleDomain, 'addHrefLangHeader'));	
}

add_action('init', 'remove_multipledomain_hreflang');

For anyone looking to use this: addHrefLangHeader got renamed to addHrefLangTags

Thanks @mytran for the heads up. I forgot about this issue when changed the action name.
