Session database not working, using cookies does

Have you extended the session class at all?

Please post your database schema.

Here's mine:

Code:

CREATE TABLE `ci_sessions` (
  `session_id` varchar(40) collate utf8_unicode_ci NOT NULL default '0',
  `ip_address` varchar(16) collate utf8_unicode_ci NOT NULL default '0',
  `user_agent` varchar(50) collate utf8_unicode_ci NOT NULL,
  `last_activity` int(10) unsigned NOT NULL default '0',
  `user_data` text collate utf8_unicode_ci NOT NULL,
  PRIMARY KEY  (`session_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;

Does yours differ in any way? There is no default set for the userdata, but mine seems to work without that. Which database and storage engine are you running?
