Thanks @Matteo Beccati for your collaboration.

with Plesk I don't think I can create a path on the server, just in the websites' root

Thanks for the reply but actually I am not capable of doing what you are suggesting. I have a plesk access but I am not confortable with linux command line. I could get some assistance though. Is this directory supposed to be created in the root of the server or in the web domain root?

Hello, when trying to install Revive AdServer I immediatelly get this error: The session save path '/var/lib/php/session' is not writable. I actually don't even see this directyory, it does not exist. any suggestion? thanks
