title: Website automatically minifies? CSS changes wont appear
body: <p>I have a big problem on my website. <br>
  When i am making changes to the CSS files nothing changes on the website.<br>
  It looks like my site is using a other CSS file u can see it here:</p>
  
  <p><a href="https://i.stack.imgur.com/Zlcc6.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Zlcc6.png" alt="enter image description here"></a></p>
  
  <p>My website is using that CSS file while this CSS file is the correct one:</p>
  
  <p><a href="http://quasarwheels.com/wp-content/themes/gilbertson/style.css" rel="nofollow noreferrer">http://quasarwheels.com/wp-content/themes/gilbertson/style.css</a></p>
  
  <p>I did include this in my header for getting the CSS file</p>
  
  <pre><code>    &lt;head&gt;
      &lt;meta charset="&lt;?php bloginfo( 'charset' ); ?&gt;"&gt;
      &lt;meta name="viewport" content="width=device-width"&gt;
      &lt;title&gt;&lt;?php bloginfo(‘name’); ?&gt;&lt;/title&gt;
      &lt;link rel="profile" href="http://gmpg.org/xfn/11"&gt;
      &lt;link rel="pingback" href="&lt;?php bloginfo( 'pingback_url' ); ?&gt;"&gt;
          &lt;link rel="shortcut icon" href="&lt;?php bloginfo( 'url' ); ?&gt;/favicon.png"&gt;
      &lt;link rel="apple-touch-icon" href="&lt;?php bloginfo( 'url' ); ?&gt;/favicon.png"&gt;
      &lt;link rel="stylesheet" href="&lt;?php echo THEME_URL;?&gt;/bootstrap/css/bootstrap.min.css"&gt;
  &lt;?php if(is_singular('frame')) {?&gt;
      &lt;link type="text/css" rel="stylesheet" href="&lt;?php echo THEME_URL?&gt;/css/font-awesome.min.css" /&gt;
          &lt;link type="text/css" rel="stylesheet" href="&lt;?php echo THEME_URL?&gt;/css/bike-builder.css" /&gt;
      &lt;?php }?&gt;
          &lt;link type="text/css" rel="stylesheet" href="http://quasarwheels.com/wp-content/themes/gilbertson/style.css" /&gt;
      &lt;!--[if IE]&gt;
          &lt;style type="text/css"&gt; #mtb, #rac, #rat, #track, #rct, #rcc{   margin-top: -55%!important;}&lt;/style&gt;
      &lt;![endif]--&gt;
          &lt;?php wp_enqueue_script("jquery"); ?&gt;
  
          &lt;?php wp_head(); ?&gt;
      &lt;/head&gt;
  </code></pre>
  
  <p>Thanks for your time!</p>
