回答1:

Have you upgraded from a 1.7 version of CodeIgniter to a 2.0 version? And are you storing sessions in a database table? And are you using IE? If so, I had this same problem. It was fixed when I edited the session table, user_agent field to a varchar(255). It's an issue with IE.

See this for the answer for this problem : Losing a session variable between one page with codeigniter session library

To sum up, you had missing resource(s) file.

Good luck!
