ログアウトのリンクはmethodを指定
view.erb
<%= link_to 'Logout', destroy_user_session_path, :method => :get, remote: true %>
config/initializers/devise.rb
config.sign_out_via = :delete
⬇️変更
config.sign_out_via = :get
ルーティングをしっかり確認
routes.rb
devise_for :users
下記を追加（なかったら）
application.js
//= jquery
//= jquery_ujs
下記を追加（なかったら）
views/layouts/application.html.erb
<%= javascript_include_tag 'application', 'data-turbolinks-track': 'reload' %>
以上
