Drupal 7 log-in form doesn't react
There is something wrong with your HTML: 

&lt;div id="node_container" &lt;form="" action="/dev_v2/kw/user" method="post" accept-charset="UTF-8"&gt;&lt;div&gt;&lt;div class="form-item form-type-textfield form-item-name"&gt;


This is definitely not interpreted as form.
