Scusatemi ma sto scapocciando posso chiedere aiuto per un login?

io ho fatto:

PHP:

<?php require_once('../Connections/centergym.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}
?>
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
  session_start();
}

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
  $_SESSION['PrevUrl'] = $_GET['accesscheck'];
}

if (isset($_POST['nome_utente'])) {
  $loginUsername=$_POST['nome_utente'];
  $password=$_POST['password'];
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "inserimento.php";
  $MM_redirectLoginFailed = "registrazione.php";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_centergym, $centergym);
  
  $LoginRS__query=sprintf("SELECT username, password FROM login_aquagym WHERE username=%s AND password=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); 
   
  $LoginRS = mysql_query($LoginRS__query, $centergym) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  if ($loginFoundUser) {
     $loginStrGroup = "";
    
	if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;	      

    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];	
    }
    header("Location: " . $MM_redirectLoginSuccess );
  }
  else {
    header("Location: ". $MM_redirectLoginFailed );
  }
}
?>

e in locale funziona alla perfezzione, ma quando pubblico mi restituisce:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /htdocs/public/www/prenotazioni/loigin.php:2) in /htdocs/public/wwwmiosito/loigin.php on line 38.

e se mi loggo ugualmente mi da:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /htdocs/public/www/prenotazioni/loigin.php:2) in /htdocs/public/www/miosito/loigin.php on line 38

Warning: Cannot modify header information - headers already sent by (output started at /htdocs/public/www/miosito/loigin.php:2) in /htdocs/public/www/prenotazioni/loigin.php on line 71

potete aiutarmi gentilmente?
saluti a tutti.

Ciao,
prova ad eliminare il seguente codice che trovi alla riga 38

PHP:

if (!isset($_SESSION)) { 
  session_start(); 
}

e spostalo in alto ad inizio pagina.

PHP:

<?
if (!isset($_SESSION)) { 
  session_start(); 
} 
?>

ciao max avevo già provato ma nulla non funzionava

Qualche correzione generale:

PHP:

<?php
if (!isset($_SESSION)) {
    session_start();
}

require_once __DIR__ . '/../Connections/centergym.php';

if (!function_exists('GetSQLValueString')) {

        switch ($type) {
            case 'text':
                $value = $value != '' ? "'{$value}'" : 'NULL';

                $value = $value != '' ? doubleval($value) : 'NULL';
            break;

            case 'date':
                $value = $value != '' ? "'{$value}'" : 'NULL';

                $value = $value != '' ? $definedValue : $undefinedValue;
            break;

    ); 

    $LoginRS = mysql_query($LoginRS__query, $centergym) or die(mysql_error());
    $loginFoundUser = mysql_num_rows($LoginRS);
    
    if ($loginFoundUser) {
        $loginStrGroup = "";

Se il file viene richiamato direttamente è difficile che non funzioni.
