Please provide solution for this issue
It happens because the action that took you to that page was a POST request. The browser wants to save you from unintentional double-ordering/paying/whatever when you go "back", when loading that page would need to do the form posted again.
How to work that around? I usually redirect the user to a page which was loaded by a GET request, it can be even the same page, see this answer: https://stackoverflow.com/a/3968038/357403
Or, you could modify the history: https://developer.mozilla.org/en-US/docs/Web/API/History_API
Also, please see the PRG pattern: https://en.wikipedia.org/wiki/Post/Redirect/Get
Try this code format:
$this->load->view('admin/home.php', 'refresh', $data);
or
redirect('home', 'refresh');
