Prestashop 1.4: permission for the directory

[Ronaldo Perez]

Where can I read about the permissions on the directories necessary for version 1.4?
Set all the required permissions, but for the directory cache to get the administrative part of the message, "Set write permissions to the directory cache", despite the fact that it set permissions 0777 (I also tried to set write permissions for subdirectories)
In the wiki on this hearth nothing.

You may need permission to write more for some directories, which are not mentioned in the administrative side?

P.S. I wrote a small "dummies" script in russian forum to change permissions on the directories that require prestashop

P.P.S. sorry for my english, i'm using Google translate
