If you are referring to the Forgot Password link in the SCLogin module, we are just redirecting to the Joomla users component (or whichever component you've set in the the SCLogin module for Registration Component). JFBConnect/SCLogin doesn't actually have any functionality for resetting the password. I'd also suggest disabling all of the JFBConnect plugins and test whether you're still having problems using the reset password functionality. If you still think this is related to JFBConnect/SCLogin, please let us know and your reasons for why.
