I've never actually used this plugin, and obviously nobody else has tried using it in a while, as it was still trying to use v1.2 of the API (they're up to 3.0 now).
Anyway, I've updated it, and fixed what appeared to be a bug. Not sure looking at the code if the setting for the URL (to override using the default details link for that form) would actually work, looks like it's always going to use the details link. But at least basic functionality should actually work now.
The fblike seems to still work. I added 'include share button' as an option (which FB seem to have added since the fblike plugin was written). Hard to know for sure, as I can't 'like' anything from my local test setup (FB obviously doesn't like the 'http://localhost'), but it's at least trying to do what it should.
But... I didn't test the fblike cos I dont have it installed. I'm not sure whether to use it or not cos I'll need to also add the share buttons of other social media platforms which means I would still have to add some third party page sharing code to the website and if it does the same thing as the fblike then there is no point installing the fblike button.
Does the fblike do anything different or extra apart from the regular page sharing/like?
