i got blank pages (white empty pages) when load website

what wrong code?

please advance!!!

here solution froentend_controller , my_controller i've change bellow work on linux hosting 1, renamed: file frontend_controller : frontend_controller 2, renamed: file admin_controller : admin_controller notes: have remember c first character of file name , class in file name have capital letter above centanc. , when extends other controller have call keep format

example: my_controller.php

 class pages extends frontend_controller{        public function __contruct(){        parent::__construct(); } } 

pages.php {pages controller}

 class pages extends frontend_controller{        public function __contruct(){        parent::__construct(); } } 

admin

class admin extends admin_controller{       public function __contruct(){            parent::__construct();     } } 

note: if named file , class named wrong blank pages (empty pages) when load site
