title: Lumen simple route request doesn't work
body: <p>I installed Lumen on my web server, but I have problems with routes</p>
  
  <pre><code>// http://12.345.678.910/
  $app-&gt;get('/', function() use ($app) {
      return "This works";
  });
  </code></pre>
  
  <p>But in this second case he cant find directory</p>
  
  <pre><code>// http://12.345.678.910/api
  $app-&gt;get('/api', function() use ($app) {
      return "This dont work";
  });
  </code></pre>

  </code></pre>
  
  <p>I use Apache, Ubuntu, PHP 5.5 and Lumen</p>
