drupal 7.34 cannot rearrange form component and others I have a fresh installation drupal 7.34 the install module ctools views and webformm. I cannot rearrange the form component. Both weight and the + symbol appear. Normally in the previous version I can switch using weight or drag the component to rearrange. How can I rearrange the form components. This problem also in other similar list, such as menu.
Very lucky...., 
I found the answer to solve the problem (related to missing misc/jquery.cookie.js) from  this discussion https://www.drupal.org/node/1052372

To solve that: Configuration > Development, enable Aggregrate Javasript file



Now it just works perfectly as in the previous versions. Thanks Drupal developers.
