    Post Action controller on localhost error?

    I think I asked that question the right way... I am getting an error while following this tut http://net.tutsplus.com/tutorials/ru...-active-admin/ I am on the step where you connect to localhost localhost:3000/admin where it is supposed to be a login form the page is screwed up...

    I am sure I am most likely doing something stupid or I'm missing something but any insight would help me a lot... Thanks

    I believe that the newest version of Formtastic (which is required by active_admin) breaks active_admin.

    1.) Add the following to your gemfile

    Code Ruby:
    gem "formtastic", "~> 2.1.1"

    2.) Then run bundle update formtastic from the command line.

    3.) Restart your server and let us know if it works!
