I’ll look asap trying to go deep further into the plugin. Thanks for your work.
WordPress considers underscored meta as ‘protected’. That’s means you can’t modify them in the admin page using the Custom Fields metabox but only through functions. Unprotected metas instead, appear in mentioned metabox as freely editable by users. So something like “id” should be protected where something like “subtitle” could be unprotected. Some must be protected for obv reasons, where sometimes it’s just a design choice.
Thank you, issue solved. Glad for the github stuff.
Unfortunately i’m having a more serious issue with taxonomies.
I’m going to open another ticket with all my thoughts and debug info.
