How it works?

Hello!
1. I'm installed module "Form page title" for change Title page "Create Question" (/node/add/answers-question). This content type adds module Answers 4.0-rc2.
2. I edited settings.php:

$conf['form_page_title_forms'] = [
  'answers_question_node_form' => 'Ask a Question',
];

3. Where profit?
