[Plugin: WP-CodeBox] pre tags not being processed at all

I’ve installed and activated wp-codebox without any issues but when it comes to processing the pre tags, nothing happens. The headers look to be set correctly:

<!– Start Of Script Generated By CodeBox –>
<link rel=”stylesheet” href=”http://staging.zamarreno.com/wp-content/plugins/wp-codebox/css/codebox.css&#8221; type=”text/css” media=”screen” />
<script language=”javascript” type=”text/javascript” src=”http://staging.zamarreno.com/wp-includes/js/jquery/jquery.js”></script&gt;
<script language=”javascript” type=”text/javascript” src=”http://staging.zamarreno.com/wp-content/plugins/wp-codebox/js/codebox.js&#8221; ></script>

<!– End Of Script Generated By CodeBox –>

But in the html generated, there’s no substitution of the pre tags. They appear just like I wrote them in the editor.

Any ideas on how to debug this or what might be the cause? I searched but found no one with the same issue
