Rails 4.0.2
When I try to create a new record in the users table i get this message in browser:

ActionController::InvalidAuthenticityToken in UsersController#create
ActionController::InvalidAuthenticityToken

But it happens in Chrome(32.0.1700.107) and Opera(12.16) browsers. In Firefox(27.0.1) and IE 10.0.13 all works fine. Maybe it does not matter, but i have to say that also i use has_secure_password(bcrypt_ruby).

Rails Log:

I just had to put protect_from_forgery in the Users controller. Thanks to all.

class UsersController < ApplicationController
  protect_from_forgery

  def index
    #@users = User.all.includes(:roles)
    @users = User.all
  end
  def show

  end
  def new
    @user = User.new
  end
  def create
    @user = User.new user_params
    puts @user.errors.inspect
    if @user.save
      flash[:notice] = "Пользователь удачно создан"
      redirect_to :users
    else
      flash[:notice] = "Пользователь не создан"
      render file: :'users/user_error'
    end
    flash["notice"] = "Test notice"
    #redirect_to :users
  end
end
