After user logs in, the news from the database wont display

[eluser]balboa_1990[/eluser]
In my application, the user can create an account, log in and it should display news articles from the database. When the user logs in now however, it displays the method/function name in the url instead of admin/news and does not display the data from the database (only the the header and links from the view). Any help would be appreciated.

Code:

CONTROLLER:

class Login extends CI_Controller {

  public function __construct() {
   parent::__construct();

  }

   public function index() {
    $data['main_content'] = 'login';
    $this->load->view('include/template', $data);
  }
  
  
  //Validate login area
  
  //This method will have the credentials validation
  public function login_validation() {
   $data['error'] ="Invalid Username or Password";
   $this->load->library('form_validation');
   $this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean|callback_username_check');
   $this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_password_check');
  
     if($this->form_validation->run() == FALSE)
      {
     //Field validation failed.  User redirected to login page
     $this->index();
    
     }else{
      $this->load->model('register_model');
      
     if($query = $this->register_model->validate()) {
     $this->load->model('news_model');
    
     $data = array('news' => $this->news_model->getArticle());
     $data['title'] = 'Admin | Home';
     $data['heading'] = 'News Articles';
     $data['main_content'] = 'admin/news';
     $this->load->view('include/template', $data);
    
     }else {
        $this->load->view('login',$data);
     }  
      
   }
}


//Validate signup area
  
  public function signup() {
   $data['main_content'] = 'signup';
   $this->load->view('include/template', $data);
  }
  
  public function create_member() {
   $this->load->library('form_validation');
  
   //field name, error, message, validation rules
   $this->form_validation->set_rules('first_name', 'Name', 'trim|required');
   $this->form_validation->set_rules('last_name', 'Last Name', 'trim|required');
   $this->form_validation->set_rules('email_address', 'Email Address', 'trim|required|valid_email');
  
   $this->form_validation->set_rules('username', 'Username', 'trim|required|min_length[4]');
   $this->form_validation->set_rules('password', 'Password', 'trim|required|min_length[4]|max_length[32]');
   $this->form_validation->set_rules('password2', 'Password Confirm', 'trim|required|matches[password]');
  
   if($this->form_validation->run() == FALSE) {
  
   $this->signup();
  
   }else{
    $this->load->model('register_model');
    if($query = $this->register_model->create_membership()) {
     $data['main_content'] = 'signup_successful';
     $this->load->view('include/template', $data);
    
    }else {
    
     $this->load->view('signup');
    }
   }
  }

}

VIEW for news

Code:

<?php foreach ($news as $article): ?>
            <h2>&lt;?php echo $article['title'] ?&gt;</h2>
                <p>&lt;?php echo $article['content'] ?&gt;</p>
                <p>&lt;?php echo $article['author'] ?&gt;</p>
                <p>&lt;?php echo $article['date'] ?&gt;</p>
                
                &lt;?php endforeach ?&gt;

News Model:

Code:

class News_model extends CI_Model {

  public function __construct() {
   parent::__construct();
  }
  
  function getArticle () {
   $this->db->select('*');
   $this->db->from('news');
   $this->db->order_by('id', 'DESC');
   return $this->db->get()->result_array();
  }
}

Been struggling most of today and i fixed one bug for this application and another happens, typical! No error message are being displayed or in the php log.
