My PHP files used to work fine on ES3, but the same files give me trouble on ES4 ... The problem is with the "session_start()" method that I have called in my php file ...

The error on ES4 says "Permission denied (13) : ...."

Has this something to do with the rights on "/var/lib/php/session" folder ... ??
they are "rwxrwx___" and the user is not root.

Also, I do not see any such folder on ES3 ....

Thanks for help.
