Ошибка сеанса PHP-страницы

Question

У меня есть страница с сеансом на ней. Когда я получаю доступ к странице с другой страницы в тот же сеанс, она выдает эту ошибку:

Предупреждение: session_start() [function.session-start]: Не удается отправить ограничитель кеша сеанса - уже отправленные заголовки (вывод запущен в/home/cooperat/public_html/администратор/applyforloan.php: 4) в /home/cooperat/public_html/admin/applyforloan.php по линии 7

Я работаю с мечтой. Пожалуйста, что, по-вашему, пошло не так?

Answer 1

Кажется, что вы запустили сеанс в другом месте, убедитесь, что session_start(); вызывается один раз на вашей странице, включая включенные php-файлы.

Я предполагаю, что applyforloan.php включен.
