User can't delete his own account , Rails 4 + Devise

I have Ruby on Rails 4 application also I am using Devise gem to provide login/register.

Everything works just fine, but users that are logged in can't delete their own account. Any other delete functions work, so Javascript shouldn't be a problem.

In view:

  <%= link_to "Delete account", registration_path(resource_name), data: { confirm: "Your profile will be permanently deleted. Are you sure?" }, method: :delete%>

I am overriding default devise Registration controller with this:

class RegistrationsController < Devise::RegistrationsController 
    clear_respond_to   
    respond_to :json

    protected

  def update_resource(resource, params)
    resource.update_without_password(params)
  end
end

My log file:

Description:

When user pushes delete button, user gets message :

translation missing: ru.devise.registrations.user.destroyed

also he is logged out from his account, but the actual destroying never happens. What could be possible problem?

Thanks for your time. Best wishes.
