Body: <p>For some reason none of the mailing settings seem to be accessible for me anymore. When I go to e.g. Administer > CiviMail > Mailer settings all I get is a blank screen, and it's the same for other mailing settings as well. We haven't been able to find why the settings aren't visible anymore so any advice would be much appreciated.
  We're running on CiviCRM 4.7.15 and Drupal.</p>
  
  <p>Thanks,

  If you use drush, `drush cc civicrm`. If that doesn't work, you could delete everything inside of the templates\_c folder.
  
  `rm -r /[path/to/drupal_root]/sites/default/files/templates_c/*`
