Try this code working fine check codeigniter version

Just go to 'system' > 'core' > 'CodeIgniter.php' and look for the lines,

/**
 * CodeIgniter Version
 *
 * @var    string
 *
 */
    define('CI_VERSION', '3.0.0');

Alternate method to check codeigniter version, you can echo the constant value 'CI_VERSION' somewhere in codeigniter controller/view file.

<?php
    echo CI_VERSION;
?>
