 * To add to my previous message. It only does this with posts. I was able to succesfully
   add a page to the Knowledge base. I have a website with custom ACF post types.

 * Hi [@zevchafer](https://wordpress.org/support/users/zevchafer/) ,
 * Thank you for the detailed bug report! I can see exactly what’s causing this 
   issue – it’s related to how we handle ACF relationship fields that return WP_Post
   objects.
 * 
   Apologies for the inconvenience. We’ve identified the fix and will have a patch
   ready within the next few days that will resolve this completely.
 * 
   I’ll update you here once the patch is available.
 * 
   Thanks for your patience!Best regards,
 * Maxwell
