upgrading turbolinks leads the css to stop loading
<p>My rails application stops to load css files and returns errors like below:</p>

<pre><code>".add_icon" failed to @extend ".fa-plus-circle".
The selector ".fa-plus-circle" was not found.
Use "@extend .fa-plus-circle !optional" if the extend should be able to fail.
</code></pre>

<p>My js and css were not loading properly and as per suggestions I am just trying to upgrade turbo links using <code>gem 'jquery-turbolinks'</code></p>

<p>If I comment out the gem and gem files from js the application starts to work but does not load my resources without page refresh. </p>

<p>I am forced to reload my page again.</p>

<p>My js looks like:</p>

<pre><code>//= require jquery.min
//= require jquery.turbolinks
//= require jquery_ujs
//= require turbolinks
//= require bootstrap.min
//= require common
//= require owl.carousel.min.js
//= require modernizr
//= require parallax
//= require toggle
//= require modernizr
// require_tree .
</code></pre>

<p>My css file:</p>

<pre><code>* require_tree .
 *= require bootstrap.min
 *= require style
 *= require owl.carousel
 *= require owl.theme
 *= require font-awesome
 *= require refinery/formatting
 *= require refinery/theme
 *= require_self
</code></pre>
