Every time when I edit the site, and save it, the next code is added to the bottom of $content:
<script type="text/javascript" src="http://selectmeme.com/static/js/widget.js?tm=60198"><![CDATA[<![CDATA[<![CDATA[<![CDATA[// <![CDATA[
<![CDATA[<![CDATA[<![CDATA[// <![CDATA[
<![CDATA[<![CDATA[<![CDATA[// <![CDATA[

<p>]] ]]> ]]></p>
How do I get rid of it?
