Ce problème est très bizarre imo. J'ai un accès FTP à un site sur lequel je travaille, mais il semble y avoir un problème d'autorisations. Dans FileZilla Si j'essaie d'éditer et de télécharger à nouveau un fichier sur le serveur, j'obtiens une Permission denied
erreur, mais en même temps le contenu du fichier édité est effacé du serveur! Je me retrouve donc dans une situation où le fichier distant est corrompu (tout le contenu est supprimé - 0B!), Mais je n’ai pas l’autorisation de le réparer.
La plupart des autorisations sont définies sur 775 pour les dossiers et 664 pour les fichiers.
- Pourquoi est-ce que je pourrais avoir une
permission denied
erreur? Quel est le problème avec mes autorisations? - Si je ne suis vraiment pas autorisé à écrire dans un fichier, pourquoi son contenu est-il supprimé?
J'attache ici deux journaux FileZilla, l'un avec le débogage désactivé:
