Purge doesn't work

Hello. Clearing the cache does not work. When you delete the cache manually at http://test/purge/post-link, then everything works fine. If we add a new comment or write, then clearing the cache does not occur. The logs nginx helper shows that removed successfully, but actually clearing the cache does not occur.

nginx 1.4.7
wordpress 3.8.1
nginx helper 1.8

Can you verify purge-settings in nginx-helper?


You need turn ON comment related checkboxes in above screenshot.
