I upgraded to latest version of W3TC today, and it seems Page cache has stopped working. There are no error messages or notifications, I can just see that in SRC that its outputting updated content for each page view.
Page cache ENABLED: http://d.pr/i/guwR
Standard cache settings: http://d.pr/i/ebG0
Yet, when you check a page, regardless of being logged in or not, you can clearly see minify is working but it is not caching pages (view source):

Worked like a dream before update. Any ideas?
