I always liked the snap shot feature. But it disappeared on my blog around mid-December–I think about the same time the Dashboard was redesigned across WordPress. In “Extras,” the box is checked to enable them. It was checked before the redesign, and it is checked now. How can I get the snap shots back?
Dashboard -> Appearance -> Extras
These are general extras that you can enable for your entire blog.
___ Enable Snap Shots on this blog
Insert a check mark in the spot prior to “Enable… “
Then click “Update Extras”.
If doing that does not work then you will need staff assistance as volunteers do not have backend access to blogs. If that’s the case then please click and file a detailed support ticket at this link http://support.wordpress.com/contact/
