Hey Toni,
Most probably it isn't working because your template contains invalid html:
<html>
<head>
<link href="http://nerdyfuture.byethost24.com/templates/nerdyfuture/favicon.ico" rel="shortcut icon" type="image/vnd.microsoft.icon" />
<style>
@media screen and (max-width:900px) { .Caption p{display: none !important;} }
@media screen and (min-width:900px) and (max-width:1200px) {}
@media screen and (min-width:1200px) {}
</style>
</head>
</html>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-gb" lang="en-gb" dir="ltr">
<head>
then
</head>
<div class="page-wrap">
<body class="site com_content view-article no-layout no-task itemid-129">
and nearly at thee end:
<!-- End Content -->
</div>
</main>
</div>
<!-- Footer -->
<div id="wrapper">
<div class="container">
<footer class="footer" role="contentinfo">
Footer
</div>
</div>
</footer>
</div>
Regards,
Daniel
