  <p>i receive this kind of error which yesterday is not showing. i didn't even change my code even the codeigniter system code.</p>
  
  <p>i tried to change my config with this code</p>
  
  <pre><code>$config['sess_driver'] = 'database';
  $config['sess_save_path'] = 'ci_sessions';
  </code></pre>
  
  <p>and put this database (based on codeigniter user guide)</p>
  
  <pre><code>CREATE TABLE IF NOT EXISTS `ci_sessions` (
          `id` varchar(40) NOT NULL,
          `ip_address` varchar(45) NOT NULL,
          `timestamp` int(10) unsigned DEFAULT 0 NOT NULL,
          `data` blob NOT NULL,
          KEY `ci_sessions_timestamp` (`timestamp`)
  );
  </code></pre>
  
  <p>but still it appears the problem
  what would be the possible reason for that and what is the solution?</p>
