title: Drupal 7 - Image Field Upload/Deletion not working
body: <p>I use Drupal 7.33 and Image Field. I can't upload or delete images when JS is turned on in my browser. So it can't be a file-permission or php problem.</p>
  
  <p>From my nginx-log-file:</p>
  
  <pre><code>[warn] 812#0: *7074 a client request body is buffered to a temporary
  file /var/lib/nginx/body/0000000023, client: 174.61.242.24,
  server: www.example.com, request: "POST /file/ajax/field_foto/und/0/form
  Bw9u5Xhbowcr3qGBI4mPYtnNtC0AUHpyi2L_xesa9qY HTTP/1.1", host: "www.example.com",
  referrer: "http://www.example.com/node/8/edit"
  </code></pre>
  
  <p>I also use the jQuery-Update Module with Version 1.5 for administrative sites.</p>
  
  <p>Console-Error:</p>
  
  <pre><code>'Attr.nodeValue' is deprecated. Please use 'value' instead.

  <p>With the default jQuery Version provided by the theme, I get this error (pop-up), when I try to delete the file:</p>
  
  <pre><code>An AJAX HTTP request terminated abnormally.
  Debugging information follows.
  Path: /file/ajax/field_foto/und/0/form-3_O5Rsz9PLD9NJCuwI157oZdHW1XJ8gOdTtJYQTT1oI
  StatusText: n/a
  ResponseText: 
  ReadyState: undefined
  </code></pre>
  
  <p>I've tested this with Chrome, Firefox and Safari.</p>
  
  <p>The Status-Report from Drupal is OK.</p>
  
  <p>Thanks for your help ;)</p>
