facebook like button show error

On Like Button Documentation I want to get Like Button Code. The Url to like is "http:/开发者_StackOverflow/tour.suiis.com/TourDetail.aspx?scnbr=88". When I click facebook like button,it show "You Like Error".

I can't find any solution. Who can help me. Thanks!

It's possible that the URL isn't reachable to Facebook. Try Facebook's URL linter to make sure.
