About BestSellers on the homepage

I have been deploy enter system, I entered configrution page with admin then set up 'show BestSellers on the home page'. but the BestSellers is not display on the home page. I look at the Dom of the page, I have not found any element about BestSellers.
Can anyone help me resolve this issue?

checked it, it works fine for me


in default.aspx
   <nopCommerce:BestSellers ID="ctrlBestSellers" runat="server" />


but remember, best sellers are chosen from products which have sold - so if you have just uploaded your store and have not put in orders through it (test or real), at the moment, there is nothing to show
