Forcing Portrait

Guys,
I am trying to force a page to show in portrait instead of landscape however it doesn't appear to be working. Heres the code I am using:

$client = new Pdfcrowd('*USERNAME*', '*API_KEY*');
$client->setPageWidth('8.5in');
$client->setPageHeight('11in');
try {
    header('Content-type: application/pdf');
    //header('Content-Disposition: attachment; filename="test.pdf"');
    echo $client->convertHtml($reportData);
}
catch(PdfcrowdException $e) {
    echo $e->getMessage();
}

What am I doing wrong?

Your code should produce portrait -- we run your code and it works as expected.

Are you sure you are not getting a cached pdf?

I apologize, it looks like that was the case, thank you for your help.
