问题
I have an application deployed on Heroku. Everything is working fine, except for signing out. When I click the link to sign out I get this error:
"The page you were looking for doesn't exist. You may have mistyped the address or the page may have moved. If you are the application owner check the logs for more information."
For user authentiation I am using of course the devise gem, I have multiple solutions hovering around Stack Overflow however none of them worked for me. Take a look at the files below.

It might be related to jQuery.
Be sure to have the following lines in your application.js file (app/assets/javascripts/application.js), before any other entry:
//= require jquery
//= require jquery_ujs
A quick fix would be to change the signout method on devise.rb initializer (config/initializers/devise.rb):
config.sign_out_via = :get
