title: how to display errors on MAMP?
body: <p>I have MAMP, and I don't know how to display errors on it,
  when I have error on my php code it shows only blank pages,
  i have searched on Google, and I saw that I have to change it to display_errors = on on all of the folders and versions...
  and include this on my page:
  error_reporting(E_ALL);
  ini_set('display_errors', 'on');</p>
