Error when saving Campaign Widget

I am using drupal 7.26, Civicrm 4.3.4, PHP-FPM 5.3
When I first time create a campaign widget, it works fine. But If I make some changes in widget and Click any of the button (Save, cancel, save & preview...) it throws an error and brings a blank page with "data;," in address bar.

If I use the widget code to create a page in drupal, also getting the same response (blank page) and the page is not saving.
Here is the error log from civicrm
