CodeIgniter base URL not configured properly in live environment

Question

When I upload my fully working codeigniter app on live server it did not find any controller and cotroller action.

For example:

my local url is:

localhost/myapp/index.php/testcontroller/testaction

Yes, It works fine, But when I upload the same thing and url becomes:

livesite.com/index.php/testcontroller/testaction

It does not work. Shows error that cant fine the controller. I am wondering why it is happening so while it is working on local server.

controller code:

<?php
class Ajaxification extends CI_Controller{
    public function __construct() {
        parent::__construct();
        $this->load->database();$this->load->model('MAjaxification');
    }
    public function Index(){
        
    }
    public function getUserDetail(){
        $this->load->model('MAjaxification');
        $uid = $_REQUEST['uid'];
        echo $this->MAjaxification->getUserdetail($uid);
       // echo "A test response";
    }
    public function getRandomUser(){
       $top = $_REQUEST['top'];
       $left = $_REQUEST['lef'];
      // $this->load->model('MAjaxification');
     //  print_r($this->MAjaxification->getRandomDonoers());*/
        $this->db->select("users.sno,users.full_name,users.userid,users.email,users.pic");
        $this->db->from('users');
        $this->db->join('donors','users.userid=donors.userid');
        $this->db->order_by('rand()');
        $this->db->limit(51);
        $res= $this->db->get();

        foreach ($res->result() as $row)
        {
          ?> <div style="border:0px solid black; width: 31px; height: 29px; float: left;">
        <a onclick="getUserinfoDetail('<?=$row->userid?>')" href="javascript:void(0)"><img width="40" height="40" src="../profile_pix/<?=$row->pic; ?>" /></a>
    </div><?php
        }
        
    }

    private function countUsers(){
        $this->db->select("users.sno,users.pic");
        $this->db->from('users');
        $this->db->join('donors','users.userid=donors.userid');
        $res = $this->db->get();
        return $res->num_rows();
    }
    function getRandUser($f=1,$t){
       $index = rand($f, $t);
       return $index;
    }
    public function testme(){
        echo "This is a test";
    }
}
?>

I never worked with Codeigniter, but if it is similar to Kohana, you have to setup the base_url. [EDIT] Check this post from CodeIgniter forum: https://github.com/EllisLab/CodeIgniter/wiki/Automatic-configbase-url
