Plugin stopped working after latest update and WPML update

Updated wordpress to latest version, there was a new update of this plugin plus WPML.
All were done.

Now Nested Pages generates error when accessing the Pages admin menu. It displays the first row partially and then an error.

This is being logged not sure if related.

Recoverable fatal error: Object of class WP_Post could not be converted to string in /home/clicdata/public_html/wp-content/plugins/wpml-cms-nav/inc/cms-navigation.class.php on line 1032

Attempted to uninstall, reset user profile, etc. Does not have an effect.

Thank you.
