Page body is blank after WP 4.6 upgrade

When I upgraded WordPress to 4.6. Now every page that has a shortcode like this
[download id=”887″ template=”nocount”] is broken.

None of the page body displays any more. The top menu, and the page header are the there.
But all of the body and the footer are missing. Even text before the plugin shortcode is now showing up.

Here’s an example page: https://rightsizemarketing.com/marketing-guides/produce-content-faster/

If I deactivate the plugin the page looks normal again, except for the download button of course.

If you want to access the site, I’m happy to setup a Support ID.

Thanks in advance for your help
