When using the 'save and continue editing' option when creating a new post, it used to display a preview of the post at the bottom of the page, so you could see the formatting etc and make sure everything looked OK before publishing the post.
Now that seems to be gone :-(
1. is this now no longer an available option, if so, why not?
or
2. did I turn off this option somehow unknowingly, and if so, how do I turn it back on again?
thanks
