looking at the source of your page i see the following error:
<div class="icons"> <a name="fb_share" type="icon" href="#" onclick="window.open('http://www.facebook.com/sharer.php?u=<br />
<b>Notice</b>: Undefined index: REQUEST_URI in <b>C:\Domains\xf.co.za\wwwroot\index.php</b> on line <b>152</b>
it looks like the path for the page is set to use a system path instead of a web address, send a copy of the page so i can see the code generating the error.
when the icons are stacking vertically, it usually means that the container they are in does not have enough room, if you send a link to page where the icons are stacking vertically, i can troubleshoot that for you.
