Hi, I don't know how to solve this. In my drupal installation directory I have a folder called "tmp". I receive an error by drupal, I read it in the log, it says approximately: "can't write to tmp directory, because permissions are not correct". Sorry I'm traslating from italian. The permissions of tmp are 755. If I change to 777 I have no problem, but 777 is unsecure. Is 755 a wrong number for a directory? What should I put instead? thanks.
