Warning: session_start() [function.session-start]: open(/tmp/sess_b121130a147db85ab3d571daea1e0d74, O_RDWR) failed: No such file or directory (2) in /txtlist/admin.php on line 8

plik php wyglada tak:

[PHP] pobierz, plaintext 
<?
require('config.inc.php');
require('functions.inc.php');
 
define('IN_ADMIN',true);
 
session_name('txtlist');
session_start();
 
if (isset($_POST['logsub'])) {
  if ($_POST['uname'] == $cfg['uname'] && $_POST['pword'] == $cfg['pword']) {
	$_SESSION['lin'] = true;
  }
  else {
	$err = 'Invalid username or password';
  }
}
elseif ($_GET['do'] == 'logout') {
  $_SESSION = array();
  session_destroy();
}
// write header
?>
