plugin IK facebook plugin. . not working, going to wrong page

I don’t know what I am doing wrong. I activated the facebook ‘like’ with the plugin ‘Ik facebook plugin’. the set up directions instructed me to get a developers ID and code. . . but I could only get that through my MAIN facebook page, and not the fb page I want linked, so even the ‘like’ does not work at all.
