phpmailer — строка php echo вызывает 500 внутренних ошибок сервера на сервере — работает локально

Мой клиент создал сайт в Adobe Muse, и мне нужно изменить его, чтобы использовать проверенный SMTP-сервер.

Все это прекрасно работает локально, но не будет работать на сервере (не Adobe сервер). Письмо отправлено нормально, но функция email_form_submission возвращает ошибку 500.

Это на общем хостинге, так что у меня сейчас нет доступа к журналам. Какая конфигурация на сервере может вызвать эту ошибку? Я не думаю, что это ошибка кодирования, так как она работает нормально локально. Я переименовал файл htmaccess, чтобы отключить его.
