title: Can not load xdebug profile by webgrind
body: <p>I have tried to use Webgrind for profiling my application but when I click on Update button it show an error:</p>
  
  <pre><code>Could not open D:\Program Files\xampp\tmp/ for reading.
  D:\Program Files\xampp\htdocs\webgrind\library\Preprocessor.php, line 49
  </code></pre>
  
  <p>I check the permission for folder tmp and sure that it's allow full control for everyone.
  The folder D:\Program Files\xampp\tmp has file xdebug_profile.6096, mean the xdebug worked correctly (I also tested xdebug by using Netbeans with xdebug and it works normally).</p>
  
  <p>My system:</p>
  
  <p>Windows Vista</p>
  
  <p>XAMPP 1.7.3</p>
  
  <p>Webgrind 1.02</p>
  
  <p>Anyone have experience of this? Please help me!</p>
