CodeIgniter URLs not routing as expected and also encountering database connection error [closed]

If you read CodeIgniter's manual, you'll understand that the path http://mtyedjs.com/index.php/home/create_account means that you should have a controller named 'home' and a method 'create_account' inside it. Then this path will be valid path (of course if you don't have you own routes).

http://mtyedjs.com/application/views/create_account.php - this is not right. create_account.php - this is you view file, because it in the views folder. Read about the MVC-model - it'll be clear to understand what I mean. So you should load this view in your method 'create_account'; it'll be something like this:

class Home extends CI_Controller {
    function __construct() {
        parent::__construct();
    }

    function create_account() {
        $this->load->view('create_account');
    }
}
