Problema messaggi chat

Salve gente!! Mi sapete dire perchè i messaggi della chat dopo 1 minuto spariscono?
[PHP]addtochat($uid, $rid);
$timeto = 86400;
$timenw = time();
$timeout = $timenw-$timeto;
$rooms = mysql_fetch_array(mysql_query("SELECT id, name FROM ibwf_rooms WHERE id='".$rid."'"));
$rname = $rooms[1];
$nick = getnick_sid($sid);

  if ($action=="")
  {
 $check = mysql_fetch_array(mysql_query("SELECT uid FROM ibwf_chonline WHERE uid='".$uid."', rid='".$rid."'"));
    if($check[0]!=$uid){
  
  mysql_query("INSERT INTO ibwf_chat SET timesent='".time()."', chatter='".$uid."', text='".$msg."'");

}
addtochat($uid, $rid);
echo "<head>";
echo "<title>$rname</title>";
echo "<link rel="stylesheet" type="text/css" href="../themes/$theme[0]">";
$unreadpopup=mysql_fetch_array(mysql_query("SELECT COUNT(*) FROM ibwf_popups WHERE unread='1' AND touid='".$uid."'"));
if ($unreadpopup[0]<1)
{
echo "<meta http-equiv="refresh" content="20; url=chat.php?time=";
echo "".date("dmHis")."";
echo "&sid=$sid&rid=$rid&rpw=$rpw">";[/PHP]
Grazie a chi mi sa rispondere:?
