I want to add a meta description to a custom module ‘mymodule’, but this doesn’t load as expected. 
 The problem is in the active trail, when menu_get_active_trail is called inside array 1 the router_path = node/% and the title is page not found. 
 How can the active trail be fixed? 
 This works on other sites.
function mymodule_html_head_alter(&$head_elements) { // menu_get_object with load function at position 2   if ($myentity = menu_get_object('myentity', 2)) {   dpm(menu_get_active_trail());    $head_elements['meta_description'] = array(     '#type' => 'html_tag',     '#tag' => 'meta',     '#attributes' => array(       'name' => 'description',       'content' => $myentity->name,       ),     );       } }
