Hard to tell what the issue is without actually seeing the code.

If I had to guess what they did was:

  user = User.find_by(email: params[:emails])
  params[:emails].each { |email| send_recovery_email(user, email) }

Instead of:

  user = User.find_by(email: params[:emails])
  send_recovery_email(user, user.email) if user

[usr1106]

It's open source, so we should be able to see the code?
