title: Rails - couldn't find file 'jquery_ujs' with type 'application/javascript'
body: <p>I have been working on integrating a wrap bootstrap template onto an app and had the index page working without bootstrap glyphicons and then changed something and I have reversed previous changes but no longer have jquery_ujs working without this error. </p>
  
  <p>Here is my gemfile thus far:</p>
