User Steve_Ng is experiencing issues with Ember running in debug mode despite setting the environment to production. After running RAILS_ENV=production bundle exec rake assets:precompile and bundle exec unicorn -p 3000 -E production -c config/unicorn.conf.rb, the console still shows a debug message (DEBUG: For more advanced debugging, install the Ember Inspector...) inside vendor.js. Mittineague clarified that the Ember Inspector is a browser addon for debugging, but Steve_Ng pointed out that the message should not appear in production mode. sam requested that the issue be replicated on meta to further investigate.
bundle exec unicorn -p 3000 -E production -c config/unicorn.conf.rb
However when I go to the site, I saw this in the console: DEBUG: For more advanced debugging, install the Ember Inspector from https://chrome.google.com/webstore/detail/ember-inspector/bmdblncegkenkacieihfhpjfppoconhi inside vendor.js
The Ember Inspector is a browser addon to help with debugging. It is not part of Discourse and it is not something you need to run Discourse - though it can be useful if debugging is what you want to do
