I find this plugin very unreliable.
When I change the appearance of a widget in my sidebar and then check the page, the edit shows up. I then log out of the admin page and recheck the homepage and find that the edit no longer shows up.
If I log back in, the edit shows up properly. log out and the page reverts to what it looked like before the edit.
I can only assume then, that the edit will not show up properly on the public page. Because the edit only shows up properly when I am logged in to the admin page.
This is frustrating and I find that I can't trust how my edits will show up to the public.
Too bad, because I really want a workable cache solution.
