Subdomain VS Cache

Hi.
i am using this plugin for my site. But my page cache is not working for my subdomain site page. I mean first look on a subdomain page never changes. Although there is a new post. And also when I change the content of the posting, but the page still appears on the contents of the previous post / old.
How can i fix it ? i am using Wp Super Cache..
my site > tv.artikelbebas.com
