session_start故障php

Ok my site was working a while ago then this happened when I tried debugging.

session_start(): Cannot send session cache limiter - headers already sent 
(output started      at ----------------:2) in   ---------------------- on line 3

(the hyphens are the same site in the same page)

and here are the codes in the first 4 lines:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<?php 
    session_start();
    include("includes/side_reservation.php"); 
?>

and I can assure you there are no session_start() inside the side_reservation.php and anywhere else as I tried searching the file itself.

Can't figure it out anymore.

    Your doctype declaration is being output before session start is being called, resulting in the "headers already sent" message when trying to set the session header,

    Start the session before ANY output to browser.

    <?php session_start(); ?>
    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
    <?php include("includes/side_reservation.php"); ?>
