I\'m working through Michael Hartl\'s Ruby on Rails tutorial on http://ruby.railstutorial.org. I\'m having trouble with Chapter 11, specifically when attempting to delete a mic
I think you are missing one of these two.
//= require jquery
//= require jquery_ujs
I accidentally removed //= require jquery_ujs and this gave me the same problem.
Are you using both prototype and jquery in your app?
I can see that you are using jquery-rails gem, but is the prototype also present there?
Check if both are being loaded, as they clash with each other.
