SOLVED Subdirectory in update folder suddenly missing or broken

[Shasaar]

Just turn off uploadify in gsconfig...

Works like a charm, thank you a lot, now i don't need the RFM anymore, i'm always glad if i can work with the core GS instead of plugins.

The hoster changed the permissions of the folder again and i am able to work on it again, thank you for that info also.
The hoster said that i withdrew the permissions on that folder for myself and anybody else, but how can this be if it is set to 640?

Uploaded a picture with the GS upload and this time, it sets permission to 644.
I'm totally confused now about the permissions.
Is there a list that shows exactly, what permissions should be set for folders and files working with GS, especially upload folder?

I'm asking cause right now, there are so many different permissions:
example thumb folder (755), subdirectories thumb (766), htaccess and index (755), a few thumbfiles (640 - can't see them in GS-preview), some other thumbfiles (755 - can see them in GS-preview)
example uploads folder (770), subdirectories uploads (770), htaccess and index (770), new uploaded files (644), previous uploaded files (640)
example posts folder - news plugin (750), htaccess (640), news-files (755)

I'm totally lost .

Cheers and thank you in advance.
