    Looks like you are running on Ruby 1.8.7, but the code you have written is only valid in Ruby 1.9.

    If possible, I would recommend upgrading up to 1.9.3; that should fix the issue.

    If you cannot use Ruby 1.9.3, just change the line from

    key: '_blog_session'

    to

    :key=>'_blog_session'
