I have All in One SEO Pack (free) installed on several sites, all running WP 3.7.1. On some sites the All Posts dashboard has extra columns showing the status of All in One SEO settings SEO Title, SEO Description and SEO Keywords.
On other sites these columns do not show and are not listed/available in Screen Options.
I cannot find a setting that controls this. What setting determines whether or not these columns are on or off?
