Thank you very much, I did as it was shown in tutorial video, I have not changed any settings other than what has said in the tutorial video. However , I can't see view and add page. Here is a Blog Controller code. Thanks

Code:

<?php

class Blog extends Controller {
    
    function Blog() {
        
        parent :: Controller();
        
        $this->load->scaffolding('entries'); //table name is entries
    }
    
    
    
    function index(){
        
        $data['title']= "My blog ";
        $data['heading']= "Howdy Guys' what's up";
        $data['todo'] = array('abd','london','pagal','sssst', 'jjjj');
        
        $this->load->view('blog_view', $data);
        
    }
}
?>
