  <p>This is my file structure,</p>
  
  <pre><code>domain.com/
  |--larco
  |-- public_html/
  |   |--laravel
  </code></pre>
  
  <p><strong>public/index.php in laravel folder,</strong></p>
  
  <pre><code>require __DIR__.'/../../../larco/bootstrap/autoload.php';
  $app = require_once __DIR__.'/../../../larco/bootstrap/app.php';
  </code></pre>
  
  <p><strong>bootstrap/app.php file,</strong></p>
  
  <pre><code>realpath(__DIR__.'/../../larco/')
  </code></pre>
  
  <p><strong>bootstrap/autoload.php,</strong></p>
  
  <pre><code>require __DIR__.'/../../larco/vendor/autoload.php';
  $compiledPath = __DIR__.'/../../larco/cache/compiled.php';
  </code></pre>
  
  <p>My laravel version is laravel 5.2. And after I loaded '<a href="http://domain.com/laravel/public/" rel="nofollow">http://domain.com/laravel/public/</a>' link I get 'Whoops, looks like something went wrong.' issue. It would be great help if someone can look into it.</p>
  
  <p>This is the issue added in storage/logs/laravel.log</p>

    <p>production.ERROR: exception 'RuntimeException' with message 'No
