Question Recent Topics ktime-selection field redirects users to page not found.

Hi,

One of my users has pointed out that the Recent Topics ktime-selection field redirect them to a page not found. This field has the following options:
<option value="0">Since last visit</option>
<option value="4">4 Hours</option>
<option value="8">8 Hours</option>
<option value="12">12 Hours</option>
<option value="24">24 Hours</option>
<option value="48">48 Hours</option>
<option value="168">Week</option>
<option selected="selected" value="720">Month</option>
<option value="8760">Year</option>

When selected it will redirect the browser to my url with the option value, e.g selecting 4 will redirect the browser to www.surreymummy.com/4


Any ideas of why this is not working correctly? Could this be a template issue?

Thanks in advance

Jason
