Hi i have problem
Fatal error: Call to a member function on a non-object in /3w/zaridi.to/s/spagi/system/application/controllers/blog.php on line 17

Code:

<?php
class Blog extends Controller {

  function Blog ()
  {
      parent::Controller();
  
  
  }

  
  function index()
  {
    
  $data['title']="MS Rymarov";
  $data['heading']="MS RYM";
  $data['query']=$this->db->get('clenove');////line 17
  
  $this->load->view('blog_ukaz', $data);
    
  }


}
?>

Can anyone explain what is wrong?

You're not connected to your database. Either add 'database' to the libraries array in application/config/autoload.php or manually load the db in your controller.
