Headers Already Sent Error with no headers being sent

Question

Getting this stupid error over and over with absolutely no headers being sent other than this one over and over again ( prints 5 times each time page is ran )

Cannot modify header information - headers already sent by (output started at /home/xx/public_html/xx/index.php:1) in /home/xx/public_html/xx/index.php on line 1

My index.php:

<?php header('Content-Type:text/html; charset=UTF-8');
            require("load.php");?>
            <!DOCTYPE HTML>
            <html>
            <head>

My load.php:

<?php
define("ABS_PATH", $_SERVER['DOCUMENT_ROOT']);
include_once (ABS_PATH .'/assets/x/la.php');
require(ABS_PATH ."/assets/x/go.php");
///some more variables;?>

My la.php:

<?php
session_start();
header('Cache-control: private'); // IE 6 FIX

if(isSet($_GET['lang']))
{
$lang = $_GET['lang'];
}
/// more code?>

I have no idea what's going on.

EDIT: Found the issue. There was a freaking single space after my ?>. I removed it and voila, it is now fixed. Thanks obama

`header('Content-Type:text/html; charset=UTF-8');` Why is this line required at the top of your index.php page? — Akshay, Aug 01 '15 at 10:32
Headers are sent when you output anything into a page. `session_Start` also should be at the top of a page. — u_mulder, Aug 01 '15 at 10:33
You probably have some whitespace characters before or after your php-tags. If there is only PHP content in a file, remove the end-tag. And check that the file starts with — Karl, Aug 01 '15 at 10:34
@u_mulder yep, but the file is actually empty. Have no idea what's going on — Mayron Mia, Aug 01 '15 at 10:40
A lot of PHP projects introduce a standard of no closing `?>` to avoid this problem. PHP will run just fine without it (so long s there's no non-php code in there), so it's safe to do and will help you avoid this stuff in the future. — Daniel Quinn, Aug 01 '15 at 10:58

You must use session_start before any headers have been sent.

Put session_start; above header('Content-Type:text/html; charset=UTF-8');

I see a whitespace here. Try this code.

<?php
session_start();
header('Content-Type:text/html; charset=UTF-8');
require("load.php");?>
<!DOCTYPE HTML>
<html>
<head>

Also, your session must be started before you send any headers.

`Parse error: syntax error, unexpected 'header' (T_STRING)` is the error im getting with your solution – Mayron Mia Aug 01 '15 at 10:41
I forgot to add a `;` in swiftness. Try again, please. – Akshay Aug 01 '15 at 10:42
