How to enable electric-pair-mode in emacs 24

Question:

Tag: emacs,autocomplete

I have enabled electric pair mode according to instructions on this page: http://ergoemacs.org/emacs/emacs_insert_brackets_by_pair.html , i.e. adding these lines to ~/.emacs:

;; autocomplete paired brackets
(electric-pair-mode 1)

But this doesn't take any effect, I still have to M-x electric-pair-mode to activate it. Why is this happening?

Emacs version is 24.3, on Mac OSX.

Here is my entire ~/.emacs
