title: PHP is processed but displaying blank page in Apache Ubuntu 13
body: <p>I have LAMP installed on my Ubuntu. In the /var/www folder I copied a directory. when I access that directory using localhost/directory_name it displays the index.php and its content too. But when I navigate to any other file it displays nothing but a blank page. But I think it is processing PHP cause when navigate to the area which needs login it redirect me to the login page. Here are the screenshots of the problem:</p>
  
  <p>This is a index.php page:</p>
