Did you try ‘view source’ and look at teh code?
It’s your slideshow, adding in some code ABOVE the <head> calls, which is screwing it up. Whatever plugin is adding this:
<link rel="stylesheet" type="text/css" media="screen" href="sidebanner.css" />
<script type="text/javascript" src="js/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="js/jquery.cycle.all.js"></script>
<script type="text/javascript">
$(function() {
$('#slideshow').before('<div id="nav" class="nav">').cycle({
fx: 'fade',
speed: 'fast',
timeout: 3000,
pager: '#nav',
before: function() {
if (window.console) console.log(this.src); }
});
});
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "https://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
is doing it.
And no, it’s not nextgen.
BTW, is this a Multisite question at ALL?
