I have created custom post type
Created custom fields
wrote post, filled custom fields.
No result in post.
When I return to the post the custom fields are not visible.
Go to add new post and custom fields are there.
Deactivated all other plugins, changed to wp twenty theme - problem persists.
I have created a staging site where you can have a look.
The staging site is password protected.
The same user and password to access login and wp admin
