I was creating a new page today on my AlexNavas.com site and noticed that the Page Details option was gone. I thought that it may be broken due to another plugin I have installed but as I went and removed all the plugins, the problem was still present. Everything below the content area including the Page Details options, Comments, Excerpt and Sharing were gone. The only details that were under the content area was the revisions.
Comments
Check in "Screen options" in top right corner while editing post. It is probably unchecked there.
With regards.
