I can’t right click the provided page. Is this supposed to be the case?
First and foremost, have you validated your code?:
Based on pages source code, the following is appended to the end of your page within the body tags:
<li class="page_item page-item-1156">
<a href="http://fruitcity.co.uk/about-2/" title="About">About</a>
I was expecting it to be a misplaced widget but the list does not have a class, id or typical parent div.
I can’t tell you why it’s occurring but I can tell you how to figure out why it’s occurring.
Sequentially disable blocks of code pertinent to that page and theme. e.g. style.css, functions.php and custom templates.
By process of elimination you’ll stumble upon the root of the issue. i.e. when the list no longer appears.
I’m ruling out that it’s a setting in the admin panel because the list doesn’t have an id or class.
It might be wise to run the validation checks I suggested. It could be something rudimentary like an element requiring a closing tag.
I’d tell you more if I could right click the page and use Chrome’s version of Firebug for property inspection.
My guess is you were running an out of date install or insecure plugin or theme. You’ll want to go through your site’s code and find what was exploited.
