In some articles K2 button does not work, look at this article :

When you press the button, the input window appears and disappears immediately
On others, the button works properly:

Thanks for your help
It seems like just a timing issue. Facebook had not scanned that page fully yet, so they weren't allowing the Like button to be clicked.
If you run a page that has issues through their Facebook URL Debug Tool and then reload the page, it should work. Otherwise, just wait a few days and the pages that don't work should start working on their own.
Hope that helps,
