I'm getting this same issue. Here's my server error: Completed 500 Internal Server Error in 6ms NoMethodError (undefined method `include?' for nil:NilClass): app/models/user.rb:57:in`new' app/models/user.rb:57:in `add_user_to_mailchimp' app/controllers/registrations_controller.rb:6:in`create'

Thanks for posting Paul, I forgot to update this. I found the line causing the error was this line in the app/model/user.rb file: Rails.logger.info("MAILCHIMP SUBSCRIBE: result #{result.inspect} for #{self.email}") Once...
