Эта проблема очень странная IMO. Я получил FTP-доступ к сайту, над которым я работаю, но, похоже, проблема с разрешениями. В FileZilla Если я пытаюсь отредактировать и повторно загрузить файл на сервер, я получаю ошибку « Permission denied доступе», но в то же время содержимое отредактированного файла стирается на сервере! Так что я попал в ситуацию, когда удаленный файл поврежден (все содержимое удалено - 0B!), Но у меня нет разрешения на его исправление.
Для большинства разрешений установлено значение 775 для папок и 664 для файлов.
- Почему я могу получить
permission denied? Что не так с моими разрешениями? - Если мне действительно не дано разрешение на запись в файл, почему его содержимое удаляется?
Я прилагаю два журнала FileZilla, один с отключенной отладкой:
