Using WPMS, version 3.5.1 and the latest version of TEC at the time of writing. As it stands, if TEC is deactivated on any of my sites, the edit posts/pages interface shows only a single page or post.
With the plugin activated, the issue goes away and the site works as expected.
The site lists the correct number of published, draft, trashed posts/pages but shows only one in the edit interface.
Removing TEC does not fix the problem.
Why would it cause this issue? How can I fix it?
