[resolved][Plugin: The Events Calendar] Month links broken in Calendar view

I have the plugin installed here:

http://pureattitude.yazminmedia.com/category/events

The next month and previous month links in the grid view for my calendar are broken. For example, when I click on the April 2011 link, I get this link which shows as broken:

http://pureattitude.yazminmedia.com/category/events/2011-04

However, when I select it from the drop down list it looks like this and works just fine:

http://pureattitude.yazminmedia.com/category/events2011-04

Is this something I’ve done wrong or a bug in the plug-in? And how can I fix it?

Thanks!
