How to use deactivate Webrick's SSL

Question

Last week I tried to debug with SSL activated in webbrick, but I forget how to restore the settings to default(without SSL). Every time I visit a controller, now it shows:

Answer 1

Similarly I recieved the same error after adding config.force_ssl = true in my config/locales/application.rb file

To remedy an SSL error, simply edit Rails.application.config.session_store :cookie_store, key: '_app_sessions' in config/initializers/session_store.rb

Changing the '_app_sessions' name to anything else will allow you to start your rails server without ssl and without error
