link being printed from "nowhere"
It can't be that hard to understand. There's a syntax error:

&lt;div id="link-clientes"&gt;&lt;a href="/areaclientes"&gt;ÁREA DE CLIENTES &lt;img height="14" width="14" src="/sites/default/files/pictures/clipart/key.png"&lt;/a&gt;&lt;/div&gt;


&lt;img&gt; tag is not closed. That's breaking your whole page HTML structure/well formedness.
