это проблема Codeigniter или что-то еще?

Я пишу код PHP с использованием Codeigniter. Мой скрипт работает нормально на моем локальном хосте, но когда я перехожу на сервер, некоторые части скрипта перестают работать. Своего рода простая регистрация от.

Когда я запускаю скрипт в Firefox, он показывает мне:

Соединение было сброшено
Соединение с сервером было сброшено во время загрузки страницы …
…..
…….

Эта ошибка отображается, когда я нажимаю кнопку отправки и отправляю форму
