Components->EasyBlog->Autoposting->Facebook->Standard_Settings
If a user fills out the entire form within this section, but does not save before pressing the "Login to Facebook" button, he or she will receive an error stating that AppID is required (see screencap). It is my opinion that the "Login to Facebook" button show either prompt the user to save or autosave before attempting to connect to Facebook. At the very least, the error message should at least suggest that the cause of the problem may be that the form has not yet been saved.
