Views components have disappeared to Page Manager in Drupal 7.39

I have a similar problem after updating to Drupal (7.39) and cTools (7.1.9) pagination in views is not working.
CustomMessage: The response failed verification so will not be processed.

Whether it has something to do with this :

The Ajax system now validates URLs before making an Ajax request. Existing code which uses the Drupal Ajax API in any of the standard ways should continue to work after this update. In the event you have unusual Ajax code which does not work with Drupal 7.39, you can have your code manually validate the URL in one of two ways. Either add the URL to the "urlIsAjaxTrusted" JavaScript setting (see ajax_pre_render_element() for an example) or call ajax_set_verification_header() in the Ajax callback function to mark the current URL as trusted. Only do this for URLs that you actually trust; Ajax requests in Drupal should never be made to untrusted URLs.
