Option "keep remote directory up to date" should upload changed files onto remote server. In most cases it does so, but sometimes it fails without any reason, randomly.
In sychronization window I can read "Change in ... detected..." twice. But no upload occurs.
When I manually try to upload the file, I get permission error, but the file is uploaded correctly, with correct permissions. I use group permission for writing. SFTP user is in group which has write access. The owner is different, and it should be different. The directory has owner set to my client user, I apply MY changes as 'www' user.
This bug seems to be permanent, feature seems plain broken.
In other directories, when user is equal to owner uploading sometimes work, sometimes not. Mostly works. It's very frustrating to fix non-existing bugs in my code just because WinSCP randomly refuses to upload changed files.
