    I am more than willing to pay for this answer as I have already pulled my hair out trying to fix it myself lol.

    You can see the error here

    This is the code (lines 1-26):

    <?
    include("database.php");
    include("form.php");

    class Session
    {
    var $username; //Username given on sign-up
    var $userid; //Random value generated on current login
    var $userlevel; //The level to which the user pertains
    var $time; //Time user was last active (page loaded)
    var $logged_in; //True if user is logged in, false otherwise
    var $userinfo = array(); //The array holding all user info
    var $url; //The page url current being viewed
    var $referrer; //Last recorded site page viewed
    var $ip; //Remote IP address

    function Session(){
    $this->ip = $_SERVER["REMOTE_ADDR"];
    $this->time = time();
    $this->startSession();
    }

    function startSession(){
    global $database;
    session_start();

    Please let me know if you can help me with this

    Regards,
    H.

    Means that something was already outputted to the browser. Can you post the entire contents of session.php?

    Use the php or code tags so that it is formatted properly on the forum.

    Try putting 

    
include("form.php");
    Code (markup):
    below the:

    
class Session
{
   var $username;            //Username given on sign-up
   var $userid;              //Random value generated on current login

   var $time;                //Time user was last active (page loaded)

   var $userinfo = array();  //The array holding all user info
   var $url;                 //The page url current being viewed
   var $referrer;            //Last recorded site page viewed
   var $ip;                  //Remote IP address  

   function Session(){
      $this->ip = $_SERVER["REMOTE_ADDR"];
      $this->time = time();
      $this->startSession();
   }

   function startSession(){

      /* Determine if user is logged in */
      $this->logged_in = $this->checkLogin();

      /* Set referrer page */
      if(isset($_SESSION['url'])){

         $this->username = $_SESSION['username'] = $_COOKIE['cookname'];
      }

      if(isset($_SESSION['username'])){
         if($database->confirmUserName($_SESSION['username']) != 0){
            unset($_SESSION['username']);
            return false;
         }

         $this->userinfo  = $database->getUserInfo($_SESSION['username']);

      } 

	  /* Return if form errors exist */

      $subuser = stripslashes($subuser);

      $this->userinfo  = $database->getUserInfo($subuser);
      $this->username  = $_SESSION['username'] = $this->userinfo['username'];

      
      /* Null login attempts */
	  $database->clearLoginAttempts($this->ip);

	  if($subremember){
         setcookie("cookname", $this->username, time()+COOKIE_EXPIRE, COOKIE_PATH);

      if(isset($_COOKIE['cookname'])){

      }

      unset($_SESSION['username']);

      $this->logged_in = false;
      
   }
}
    Code (markup):
    And you don't need a semicolon while closing function/class.

    Paste form.php as well as database.php (you can obviously hide all passwords and connection details of course) codes if you can. This would let us know what is inside them.

    I reckon that you use session_start();

    What you need to do is to make sure that this code is the first one. THe thing here is that you cannot output any text in front of session_start(); code.

    I tried to move session start to the begining of the code, but this just left me with a blank page on load.

    Try this
    
if(!isset($_SESSION)) session_start();
if(!ob_start("ob_gzhandler")) ob_start();

    Try to remove the session_start() from the form.php and database.php if its there.

    Or if its require on both/any file(s), then remove it from class function.

    hope it helps..
