Important Note for PHP with Safe Mode activated: You'll have to create /UserFiles/File, /UserFiles/Flash, /UserFiles/Image and /UserFiles/Media in order for the filebrowser to work. Of course, you'll also have to set the correct permissions for these directories. Furthermore, don't use the "Create new folder" button. The folder would be created but couldn't be used (Safe Mode restriction).
in pratica bisogna creare a mano le cartelle..
