Still getting "Current password can't be blank" in Registration Edit after following wiki

I worry the solution here will be woefully obvious, but I'm having trouble implementing the instructions on the Devise wiki (https://github.com/plataformatec/devise/wiki/How-To%3a-Allow-users-to-edit-their-account-without-providing-a-password) I'm using Rails 4. After following the wiki, I'm still receiving "current password can't be blank". Here's my setup. Any assistance is much appreciated! REGISTRATIONS_CONTOLLER.rb ``` class RegistrationsController < Devise::RegistrationsController def update @user = User.find(current_user.id) successfully_updated = if needs_password?(@user, params) @user.update_with_password(devise_parameter_sanitizer.for(:account_update)) # Rails 3: @user.update_with_password(params[:user]) else # remove the virtual current_password attribute update_without_password # doesn't know how to ignore it params[:user].delete(:current_password) @user.update_with_password(devise_parameter_sanitizer.for(:account_update)) # Rails 3: @user.update_without_password(params[:user]) end if successfully_updated set_flash_message :notice, :updated # Sign in the user bypassing validation in case his password changed sign_in @user, :bypass => true redirect_to after_update_path_for(@user) else render "edit" end end private # check if we need password to update user data # ie if password or email was changed # extend this as needed def needs_password?(user, params) user.email != params[:user][:email] || params[:user][:password].present? end end ``` APPLICATION_CONTROLER.rb ``` class ApplicationController < ActionController::Base protect_from_forgery with: :exception before_filter :configure_permitted_parameters, if: :devise_controller? def configure_permitted_parameters devise_parameter_sanitizer.for(:account_update) do |u| u.permit(:first_name, :last_name, :username, :email, :avatar, :password, :password_confirmation) end devise_parameter_sanitizer.for(:sign_up) do |u| u.permit(:first_name, :last_name, :username, :email, :password, :password_confirmation) end devise_parameter_sanitizer.for(:sign_in) do |u| u.permit(:username, :email, :password) end end end ``` ROUTES.rb ``` ProjectFoo::Application.routes.draw do devise_for :users, :controllers => { :registrations => "registrations", :invitations => 'users/invitations' } ``` Note: I'm also using the devise_invitable gem VIEWS/DEVISE/REGISTRATIONS/EDIT.html.erb ``` <h2>Edit <%= resource_name.to_s.humanize %></h2> <%= image_tag @user.avatar.url(:square) %> <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => { :method => :put, :class => 'form-horizontal' }) do |f| %> <%= devise_error_messages! %> <div class="span5"> <div class="control-group"> <%= f.label :email, :class => 'control-label' %> <div class="controls"> <%= f.email_field :email, :autofocus => true, :class => 'text_field' %> </div> </div> <div class="control-group"> <%= f.label :username, :class => 'control-label' %> <div class="controls"> <%= f.text_field :username, :autofocus => true, :class => 'text_field' %> </div> </div> <div class="control-group"> <%= f.label :first_name, :class => 'control-label' %> <div class="controls"> <%= f.text_field :first_name, :autofocus => true, :class => 'text_field' %> </div> </div> <div class="control-group"> <%= f.label :last_name, :class => 'control-label' %> <div class="controls"> <%= f.text_field :last_name, :autofocus => true, :class => 'text_field' %> </div> </div> <div class="control-group"> <%= f.label :twitter_handle, :class => 'control-label' %> <div class="controls"> <%= f.text_field :twitter_handle, :autofocus => true, :class => 'text_field' %> </div> </div> <div class="control-group"> <%= f.label :avatar, :class => 'control-label' %> <div class="controls"> <%= f.file_field :avatar, :class => 'file_field' %> </div> </div> </div> <div class="span5"> <% if devise_mapping.confirmable? && resource.pending_reconfirmation? %> <div>Currently waiting confirmation for: <%= resource.unconfirmed_email %></div> <% end %> <div class="control-group"> <%= f.label :password, :class => 'control-label' %> <div class="controls"> <%= f.password_field :password, :autocomplete => "off", :class => 'password_field' %><br><i>(leave blank if you don't want to change it)</i> </div> </div> <div class="control-group"> <%= f.label :password_confirmation, :class => 'control-label' %> <div class="controls"> <%= f.password_field :password_confirmation, :class => 'password_field' %> </div> </div> <div class="control-group"> <%= f.label :current_password, :class => 'control-label' %> <div class="controls"> <%= f.password_field :current_password, :class => 'password_field' %><p><i>(we need your current password to confirm your changes)</i></p> </div> </div> <%= f.submit "Update" %> </div> <% end %> <div class="span11"> <hr> </div> <div class="span11"> <h3>Cancel my account</h3> <p>Unhappy? <%= button_to "Cancel my account", registration_path(resource_name), :data => { :confirm => "Are you sure?" }, :method => :delete %></p> <p><%= link_to "Back", :back %></p> </div> ```
