view cart & check out page not working

Hello,
I have issue about check-out page. After I import the demo data, I noted the check out page is sticking with fashion slider. When I click “check out” at my site, the page been directed to “Fashion”titled page. The real check out page with short woocommerce code does not work.
Also when I click “view cart”, the site does not show as demo’s. Can you please let me know how I can fix these problems? My site : http://www.pawonfashion.com, thank you.
