title: "Forbidden You don't have permission to access / on this server." error msg
body: <p>i m working on a online payment module in php. I got the "Forbidden  You don't have permission to access / on this server." error msg when i make the payment and redirected to bank site only for one registered user.
  For others user module is working fine, means they makes their payment properly. 
  i m confused why only for a one perticular  registered user this msg is coming ???  </p>
