NoMethodError in SessionsController#new

You have a nil object when you didn't expect it! You might have expected an instance of Array. The error occurred while evaluating nil.+

This is nothing to do with the original subject of this thread. I suggest starting a new thread with an appropriate subject. First however examine the error message carefully and try and work out what it means. There should be a stack trace showing which line the error appeared on.
