На сайте http://visaforbali.com/ у меня не запускается cron. Ни автоматически, ни вручную.
Выдает при запуске

Cron run failed.

Уже 3 недели как не могу решить эту проблему.
Drupal новый 7.36. Все модули свежие.

На всякий случай и отключила поиск. Не помогло.

Как понять, откуда взялась эта беда с кроном и что делать?

Заранее спасибо!

UPD: помогла установка https://www.drupal.org/project/ultimate_cron
