Hi Fritz,

kannst Du den Test noch einmal wiederholen, wenn Du zuvor die Funktion user_online in der Datei functions.inc.php wie folgt ersetzt?

/**
 * counts the users that are online
 */
function user_online($user_online_period = 10) {
 global $connid, $db_settings, $settings;
 if (isset($_SESSION[$settings['session_prefix'].'user_id']) && is_numeric($_SESSION[$settings['session_prefix'].'user_id'])) {
  $user_id = $_SESSION[$settings['session_prefix'].'user_id']; 
  $ip = "uid_" . $user_id;
 }
 else {
  $user_id = 0;
  $ip = $_SERVER['REMOTE_ADDR'];
 }
 
 $diff = TIMESTAMP-($user_online_period * 60);
 
 @mysqli_query($connid, "DELETE FROM ".$db_settings['useronline_table']." WHERE time < ".$diff);
 list($is_online) = @mysqli_fetch_row(@mysqli_query($connid, "SELECT COUNT(*) FROM ".$db_settings['useronline_table']." WHERE ip= '".mysqli_real_escape_string($connid, $ip)."'"));
 if ($is_online > 0) 
  @mysqli_query($connid, "UPDATE ".$db_settings['useronline_table']." SET time='".TIMESTAMP."', user_id='".intval($user_id)."' WHERE ip='".mysqli_real_escape_string($connid, $ip)."'");
 else 
  @mysqli_query($connid, "INSERT INTO ".$db_settings['useronline_table']." SET time='".TIMESTAMP."', ip='".mysqli_real_escape_string($connid, $ip)."', user_id='".intval($user_id)."'");
}

Ist der Fehler dann weg?
