Weekly schedule not showing on website

Hello

I have use the following code to export the weekly schedule to my webpage but only the titles of the days are appearing, no other content.  The on now/next and also the single day schedules are appearing without issue.

<link rel="stylesheet" href="/airtime-widgets/css/airtime-widgets.css" type="text/css" />
<script src="/airtime-widgets/js/jquery-1.6.1.min.js" type="text/javascript"></script>
<script src="/airtime-widgets/js/jquery-ui-1.8.10.custom.min.js" type="text/javascript"></script>
<script src="/airtime-widgets/js/jquery.showinfo.js" type="text/javascript"></script>
<script>    
    $(document).ready(function() {
        $("#scheduleTabs").airtimeWeekSchedule({
            sourceDomain:"http://radio.thurrockradio.org.uk:85",
            dowText:{monday:"Monday", tuesday:"Tuesday", wednesday:"Wednesday", thursday:"Thursday", friday:"Friday", saturday:"Saturday", sunday:"Sunday"},
            miscText:{time:"Time", programName:"Name of programme", details:"Details", readMore:"Read more"},
            updatePeriod: 600 //seconds
        });
    });
</script>
<div id="scheduleTabs" style="position: relative; bottom: 100px;"></div>
