Thanks for your reply.Those posts are prior to SFC. I removed the test post last night, but I've just posted a new one just for you. This also has published on the Fanpage perfectly.
My question is, I've clicked the checkboxes for Like and Share on the SFC Plugins panel, and also selected the Like button setting I want.
I was expecting to see a like button appear at the top of any new posts ( or wherever I selected on the settings ). Is it as simple as that or am I missing something very obvious ?
