I just installed Like as per the instructions. It does work! Every time I click on the Like icon it flashes briefly with a '1', indicating that there's been a vote. But sadly after a second or so it reverts back. It's as though it's trying to communicate with Facebook and failing.
My facebook account doesn't show up a like either. Something's not working.
Also, I tried typing in my facebook numeric ID but don't get the promised Admin link...
Either I've missed something fundamental to this 'just works out the box' plugin, or it's broken.
