Hi Everyone,

Everytime I log into my website I always get the below error.

Code:
Cannot modify header information - headers already sent by ......
I thought maybe if my form submitted to another page it would work but it didn't.
I thought if I echo'ed out the header information that would work but it didn't. (instead of including it)

Below is my syntax. What am I doing wrong?

PHP Code:
<?php
session_start
();
include
"connect_to_mysql3.php";
$loggedinuser $_SESSION["id"];
$name $_SESSION["name"]; 
   
include 
'header.php';

/* echo '
