title: Woocommerce update cart button not working
body: <p>I recently updated to woocommerce 2.3.7 and now the update cart button on the cart page isn't updating the changes i've made to quantities of items.  I can still remove items but the update cart button isn't working?</p>
  
  <p>How do i solve this?</p>
  
  <p>Is this a common error as i haven't installed any new plugins and everything was working fine on the previous woocommerce version 2.0.6</p>
