Thanks for you reply,
I want to broadcast a Recipe (parent custom post type) and Ingredient (children custom post type), I’m using wp-types plugin. And yes, meta box is visible, this is the meta box debug info:
High enough role to link: yes
Post supports custom fields: yes
Post supports thumbnails: yes
High enough role to broadcast custom fields: yes
High enough role to broadcast taxonomies: yes
Blogs available to user: 7
Plugins that have hooked into save_post:
delete_get_calendar_cache
wpcf_admin_save_post_hook
WP_Widget_Recent_Posts
wpcf_fields_checkbox_save_check
wpcf_pr_admin_save_post_hook
threewp_broadcast\ThreeWP_Broadcast
threewp_broadcast\ThreeWP_Broadcast
The weird thing about this is if I remove all ingredients from the recipe works fine.
