PHP Index.php change title

In my website i cannot seem to change the title in the index.php page, i did not create this code so i did not initially make the title, the index.php looks like this `

$result = mysql_query ("SELECT * FROM news ORDER BY i DESC"); 
while ($new = mysql_fetch_assoc($result)){ $news[] = $new; }  
$smarty->assign('iplogged', $news);
$smarty->display("class.index.tpl");
$smarty->display("class.footer.tpl");
?>

` The title is vDod - Dashboard but i want to change it, i do not know how, editing anything in that code there will give me an error on all pages, stating 'Direct Access Not Allowed'

Please help, would be greatly appreciated,

Kind Regards, Charlie Land
