If you view the raw HTML of your home page, around line 260 is the following code:
<div class="tm-block-bottom">
<section class="tm-bottom-c uk-grid tm-grid-block" data-uk-grid-match="{target:'> div > .uk-panel'}">
<div class="uk-width-1-1"><div class="uk-panel">
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
</head>
<body>
<div class="uk-grid">
<div class="uk-width-1-1 uk-width-medium-2-3">
<ul class="uk-subnav uk-subnav-line tm-subnav">
<li><a href="/index.php/site-privacy" title="Privacy Policy">Privacy Policy</a></li>
<li><a href="/index.php/site-disclaimer" title="Disclaimer">Disclaimer</a></li>
<li><a href="/home/terms-of-use" title="Terms of Use">Terms of Use</a></li>
</ul>
</div>
<div class="uk-width-1-1 uk-width-medium-1-3">That's basically starting a new 'page' within the page, and it's invalid HTML markup.
I'm unsure what's causing that extra block of code, but you'll need to investigate so it can be fixed. It's very possible these duplicate head and body blocks are causing the issue you describe, but repeated head/body blocks can cause many other problems with browsers and search engines either way and should be fixed.
I hope that helps narrow things down.
Thanks,
Alex
