Загрузка файла jquery.form работает в локальной системе, но не на сервере — после отправки на сервер отображается пустая страница
Я использовал плагин jquery.form для загрузки файла (скачал код с http://malsup.com/). Он отлично работает на моем локальном компьютере, но показывает пустую страницу после отправки формы на сервер. Я установил права доступа к файлам 777 для каталога, куда должны быть загружены файлы. Код «из коробки» отлично работает на сервере. Тем не менее, я включил его в мою мобильную установку jquery и добавил операции с базой данных и формы удаления файлов. Хотя он работает как задумано локально, он отображает пустую страницу на сервере. Не отображается никаких ошибок, файлы не загружаются, база данных не обновляется. Похоже, что код обработки не выполняется вообще. Я пытался повторить что-то в начале кода обработки формы, и этого тоже не происходит, поэтому похоже, что форма ajax не отправляется.
Вот код для формы и второй для обработки.
