Bug in FrameMarket, GridMarket, or MarketPress.

When the "Browse Products »" is selected under the shopping cart it takes you to
http://myhome123.com.tw/store/products/
Then when you click next at the bottom to go to page 2 you get
http://myhome123.com.tw/store/products/?page=2
But non of the products change. You are still seeing products from page one.
