I'm guessing one of these is line 222, and you have no record for that '$id'
yet in your database.
For a brand new site, you'll need to register them first, or stick an @ in
front of these, or...
Or, just use your $numOfRows to decide if there's a value to retrieve or
not.

And this has no effect, since there are no rows with that id of '$id'

Unless there's more to this function you are not showing, you could just do:
function updateHitCounter($id,$PHPSESSID,$type){
$flag=$this->validateSession($PHPSESSID);
if($flag==1){
include("admin/config.inc.php");
$connection = mysql_connect("$host","$username","$password");
if ($connection == false){
echo mysql_errno().": ".mysql_error()."<BR>";
exit;
}
$query = "update sites set $type = $type + 1 where id = '$id'";
$update = mysql_query($query);
}
}
You could then use http://php.net/mysql_affected_rows to find out if there
was a site you even updated...
