Temporary fix works, thank you!
Don’t know why but I had to use '_wpcf_belongs_'.$parent_post_type.'_id' instead of '_wpcf_belongs_{$parent_post_type}_id' .
Same issue here.
I spent hours reinstalling my wordpress website, but after few debugs, it definitely comes from the plugin last update.
It was working great before update.

Yep, I should have found it by myself. Thanks very much !
This is because this action require the “manage_options” capability. You can use this plugin (http://shinephp.com/user-role-editor-wordpress-plugin/) to do so.
