The JFBCLike module was removed many versions ago. You should no longer be using that module.
Instead, please replace it with the SCSocialWidget module and configure it as a Facebook -> Like button. All the same options will be there, with some general improvements.
In general, the SCSocialWidget replaces almost all of the older JFBCxxx modules, like JFBCLike, JFBCFan, JFBCComments, JFBCFriends, JFBCRecommendations, JFBCRecommendationsBar. You can safely uninstall all of those modules.
I hope that helps,
Alex
