I have Facebook buttons on my detail pages, so people can "like" a listing.
Although all detail pages use the same template, I am unable to "like" some, but I can "like" others.
For example, I can "like" http://wizz.travel/submit/detail,1928316470.html
but I am not able to like http://wizz.travel/cambodia/tours-cr...908225939.html
Does anybody have any ideas why this would be?
