Getting server error 500

I am getting an error 500, and when I check the logs on GoDaddy, it says:

PHP Fatal error: Class 'CI_DB_mysqli_result' not found in /home/rahmanhabib1/public_html/portal/system/database/DB_driver.php on line 706

and when I go to DB_Driver.php on line 706,

// Load and instantiate the result driver
$driver     = $this->load_rdriver();
$RES        = new $driver($this);

also the DB driver settings for my database are set to mysqli, and hosting with GoDaddy. Can't seem to find the issue as when I run it on local host, everything seems to be fine.
