[The session save path '/var/lib/php/session' is not writable.]

Thanks @Matteo Beccati for your collaboration.

[The session save path '/var/lib/php/session' is not writable.]

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

[The session save path '/var/lib/php/session' is not writable.]

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?
