FileZilla zgłasza komunikat „Odmowa zezwolenia”, ale opróżnia plik (usuwa całą zawartość pliku)

Ten problem jest bardzo dziwny. Mam dostęp FTP do witryny, nad którą pracuję, ale wydaje się, że występuje problem z uprawnieniami. W FileZilla Jeśli spróbuję edytować i ponownie załadować plik na serwer, pojawia się Permission deniedbłąd, ale jednocześnie zawartość edytowanego pliku zostaje wymazana z serwera! Skończyło się na tym, że zdalny plik został uszkodzony (cała zawartość usunięta - 0B!), Ale nie mam uprawnień, aby to naprawić.

Większość uprawnień jest ustawiona na 775 dla folderów i 664 na pliki.

• Dlaczego mogę otrzymywać permission deniedbłąd? Co jest nie tak z moimi uprawnieniami?
• Jeśli tak naprawdę nie mam uprawnień do zapisu do pliku, dlaczego jego zawartość jest usuwana?

Dołączam tutaj dwa dzienniki FileZilla, jeden z wyłączonym debugowaniem:

Sprawdzając kod źródłowy FileZilla / PuTTY, jasne jest, że FileZilla rzeczywiście otrzymała błąd „odmowa uprawnień” podczas próby otwarcia pliku do zapisu.

Jeśli zawartość pliku została usunięta pomimo błędu, musi to być błąd / błędna konfiguracja serwera SFTP.
