I suppose libraries/Session.php is good. So the issue comes from my code or my settings.
I have added Flexi-Auth to get authentication in my software. And now, I cannot show any page in the browser.
I've empty the ci_sessions table and I've deleted ci_sessions cookie.
Not better.
To install Flexi Auth, I did : copy Flexi Auth files in the good places.
And change value of $config['security']['static_salt'] in flexi_auth.php.
Nota 1 : At the end of flexi_auth.php file, there is /* Location: ./system/application/config/flexi_auth.php */
But, there is no a application or config folder in system folder. So I copied this file to application/config/ folder.
The error is : Error Number: 1064
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'session_id`, `ip_address`, `user_agent`, `last_activity`, `user_data`) VALUES ('' at line 1

Each time I refresh the default page, wich should only show 'coucou', this number aff26d184262b8c4a915adaa40286c19 and this one 1409755863, change.
It looks like the ci_sessions does not work any more.
This issue, came before I could create my first user, then, login in is impossible.
Nota 2 : The SQL script given by Flexi Auth to create ci_session table, is not the same as the ci_sessions table I allready have :
Flexi Auth script => user_agent varchar(120) DEFAULT NULL,
My ci_session table => user_agent varchar(120) NOT NULL,
But I don't think this changes something to my issue.
Thanks for help. Nils.
