Session:transient error

Ah, now I remember, the instructions say primary key on [id, ip_address] if sess_match_ip is true else primary key only on [id]. I have sess_match_ip to false because I found on android tablets on whcih the google web speed up setting is set to true ( i forget the name they use), the session is lost because the ip changes to a google assigned one. For that reason I had to go for sess_match_ip to false
