"No posts found" error in back end

Recently our back end is not showing the posts.

If you click on “Posts,” it will say “No posts found.”

Yet we have:
All (245) | Published (239) | Scheduled (3) | Drafts (3)

The filters are set for “Show all dates” and “View all categories.”

If you click “Published” it shows the posts. Clicking on All, Scheduled or Drafts results in “No posts found.”

I updated all the plug-ins and also disabled them all to see if that had any effect. Nothing.

Any ideas, beyond starting over (re-install, etc.)?

Thanks in advance.
