Devise upgrade from 1.1.5 to 1.4.5 causes Wrong Number of Arguments error

Question

I just upgraded from Devise 1.1.5 to 1.4.5 to use with Rails 3.1 (1.1.5 seems to cause a bcrypt gem version problem).

Now user_signed_in? throws " wrong number of arguments (1 for 2)"

Stack trace is:

Anyone experiencing this?

Answer 1

I ran rake tmp:clear and changed the name of my session in session_store.rb

Woodhack::Application.config.session_store :cookie_store, :key => '_NEW_NAME_HERE_session'

You can also change one character in your config/initializers/secret_token.rb
