Could you make sure that the JFBConnect plugins are enabled? Specifically the jfbcsystem plugin and, if you want authentication, also the user and authentication plugins. We throw that message when we can't find the system plugin.
Ahhh, you are using the older JFBCFan and JFBCSend modules. Those will no longer work. Please change them each to an instance of the SCSocialWidget module. You can select Facebook as the provider and then select the Page Plugin widget (for the JFBCFan module) and Send (for the JFBCSend module).
JFBConnect not found. Please reinstall.
