Facebook like button is not working

问题

I have 2 sites where Facebook like button is not working:

http://www.mantrazdrowia.pl/przepisy/slodkosci/sernik-truskawkowy/ - I would like to like that url (tried to like it even from FB code generator - http://developers.facebook.com/docs/reference/plugins/like/ - no success) despite that its homepage: http://www.mantrazdrowia.pl/ can be liked just fine

and same applies here: http://www.shopperhive.co.uk/blog and http://www.shopperhive.co.uk/ any help ?
