I can't figure it out and it's hard to Google:

My iframe produces a "1" just before the

but I can't figure out why and where it comes from.
http://www.quepasa.in-town.nl/facebook/

My code:

require 'fb-sdk/src/facebook.php';
$facebook = new Facebook(array(
'appId' => 'xxxxxxx',
'secret' => 'xxxxxxxxxxxxxxxxxxxxxxxxxxxx',
));

$signed_request = $facebook->getSignedRequest();

$page_id = $signed_request["page"]["id"];
$page_admin = $signed_request["page"]["admin"];
$like_status = $signed_request["page"]["liked"];
$country = $signed_request["user"]["country"];
$locale = $signed_request["user"]["locale"];

if ($like_status) {
echo include("page-revealed.php");} else {echo include("page-signup.php");}

The revealed and signup have not more then this and temporary deleting everything didn't help.

Does anyone know where this is coming from?
