Hello! Make sure that you are passing to the $this-load->view( ) method the variables that are prepared in the controller. For example, in the view, you never have anything in the variable $msg because it comes from the variable $messages of flashdata, that was never defined in the controller .

Try calling the method as exemplified below and giving a echo( ) in the view. You will be able to see the variable, without appearing that nothing changes after assigning value to it. 

$data = array();
$data['minha_variavel'] = 'Charles Darwin';
// Veja: há um $data depois da string com o nome da view
$this->load->view('admin/login', $data);

And in the view: 

<h1><?=$minha_variavel?></h1>

This will display Charles Darwin in bold letters on the page.
