localization issue

i believe to have an issue like this: https://forum.codeigniter.com/thread-75292.html

I have a site in 3 language: IT EN ES

I use {locale} and all work good but only if the pages are identical.

For example: in IT and ES i display the "regular home page" but in EN i would like display a maintenance page. Something force the view and too in EN i can see the home in english.

My link:
mydomain.com/it
mydomain.com/es
mydomain.com/en

EN controller (i tried too with redirect but doesn't work):

PHP Code:

    public function index()
    {
      $data['title'] = 'My site';
      $data['metaDescription'] = '';

      return redirect()->to(base_url('en/offline'));
      //echo view('offline', $data);
    } 


IT controller:

PHP Code:

public function index()
    {
      $data['title'] = 'Il mio sito';
      $data['metaDescription'] = '';

      echo view('home', $data);
    } 


Any idea to solve? Thanks for help me.
