I am using the Ion auth library with codeigniter and have created a login, register, remember me and forgot password features (so far).

For the forgot password feature, the user types in their email address, they are then sent an email with a link to reset the password.

A page opens with them to type in the new password and confirmation password and when i click submit i get this error in my php log:

Code:
PHP Fatal error:  Call to undefined method Auth::_valid_csrf_nonce() in /Applications/MAMP/htdocs/Auth/application/controllers/auth.php on line 273

I have not changed anything when downloading this library so wondering where i'm going wrong?

Thanks

Here is my code to support this:

Auth Controller:

Code:
function _get_csrf_nonce()
    {
        $this->load->helper('string');
        $key = random_string('alnum', 8);
        $value = random_string('alnum', 20);
        $this->session->set_flashdata('csrfkey', $key);
        $this->session->set_flashdata('csrfvalue', $value);

        return array($key => $value);
    }

    //reset password - final step for forgotten password
    public function reset_password($code = NULL)
    {
        if (!$code)
        {
            show_404();
        }

        $user = $this->ion_auth->forgotten_password_check($code);

        if ($user)
        {
            //if the code is valid then display the password reset form

            $this->form_validation->set_rules('new', 'New Password', 'required|min_length[' . $this->config->item('min_password_length', 'ion_auth') . ']|max_length[' . $this->config->item('max_password_length', 'ion_auth') . ']|matches[new_confirm]');
            $this->form_validation->set_rules('new_confirm', 'Confirm New Password', 'required');

            if ($this->form_validation->run() == false)
            {
                //display the form

                //set the flash data error message if there is one
                $this->data['message'] = (validation_errors()) ? validation_errors() : $this->session->flashdata('message');

                $this->data['min_password_length'] = $this->config->item('min_password_length', 'ion_auth');
                $this->data['new_password'] = array(
                    'name' => 'new',
                    'id'   => 'new',
                'type' => 'password',
                    'pattern' => '^.{'.$this->data['min_password_length'].'}.*$'
                );
                $this->data['new_password_confirm'] = array(
                    'name' => 'new_confirm',
                    'id'   => 'new_confirm',
                    'type' => 'password',
                    'pattern' => '^.{'.$this->data['min_password_length'].'}.*$'
                );
                $this->data['user_id'] = array(
                    'name'  => 'user_id',
                    'id'    => 'user_id',
                    'type'  => 'hidden',
                    'value' => $user->id
                );
                $this->data['csrf'] = $this->_get_csrf_nonce();
                $this->data['code'] = $code;

                //render
                $this->_render_page('reset_password', $this->data);
            }
            else
            {
                // do we have a valid request?
                if ($this->_valid_csrf_nonce() === FALSE || $user->id != $this->input->post('user_id'))
                {

                    //something fishy might be up
                    $this->ion_auth->clear_forgotten_password_code($code);

                    show_error('This form post did not pass our security checks.');

                }else{
                    // finally change the password
                    $identity = $user->{$this->config->item('identity', 'ion_auth')};

                    $change = $this->ion_auth->reset_password($identity, $this->input->post('new'));

                    if ($change)
                    {
                        //if the password was successfully changed
                        $this->session->set_flashdata('message', $this->ion_auth->messages());
                        $this->logout();
                    }else{
                        $this->session->set_flashdata('message', $this->ion_auth->errors());
                        redirect('reset_password/' . $code, 'refresh');
                    }
                }
            }
        }
        else
        {
            //if the code is invalid then send them back to the forgot password page
            $this->session->set_flashdata('message', $this->ion_auth->errors());
            redirect("forgot_password", 'refresh');
        }
    }
