title: Incorrect directory separator on Windows with WordPress
body: <p>This error occurs with WordPress while uploading.  My hosting OS is Windows.</p>
  
  <p>It gives an error close to this:</p>
  
  <pre><code>Could not upload the  file ... \a\b\c\wp-content/uploads/2011/01
  </code></pre>
  
  <p>Do you know what the problem is?  How can I change the directory separator in WordPress?  (If this is the solution?)</p>
