JFBConnect automatically looks for the following file when loading the Admin Profiles area:
/plugins/socialprofiles/<YOUR_PLUGIN>/forms/config.xml
That file is where we setup any additional options to show in the admin area -- always import fields, import avatar, etc that are shown in other plugin area. Try copying one of those files to your directory to see if that gets rid of the error. Then, you can remove the fields that you don't want from the XML file.
I hope that helps get you going,
Alex
