Thread:Project:Support desk/suddenly cant upload files/reply (2)

Now I did chmod 777 for lockdir. I dont find explanation which permission for the folders is necessary. The image folder had already 777. I wonder why I was able to upload files before. But now I geht this:

Warning: failed to mkdir "/www/htdocs/user/path/wiki/images/archive/f/fa" mode 0777 [Called from wfMkdirParents in /www/htdocs/user/path/wiki/includes/GlobalFunctions.php at line 2582] in /www/htdocs/user/path//wiki/includes/debug/MWDebug.php on line 302

Das Verzeichnis (directory) „mwstore://local-backend/local-public/archive/f/fa“ konnte nicht angelegt werden. (failed to create)

EDIT: I gave chmod 777 also to wiki/images/archive/ The image got uploaded. But now I have problem with "failed to mkdir" thumbs folder ... and so on. Do all folders in directory "image" need 777? Thanks
