thanks u for the reply.
Yes I use CI sessions, but the strange thing is that try_login() register well the data but try_session_login can't retrieve it, I loaded CI session'clas in my controller, but it didn't get better. I will have more time at the end of this week to dive into the code, and will post what was my problem.
Anyway, as I began using only cookies, it worked well, and tour class can be a simple way to store some user preferences without authentication.
Thank you man!
