    Hello,

    It seems like after a recent update, Metabox's custom post types don't seem to work with Polylang's "Duplicate Content" feature.

    Basically, when you create a post, you can select this option and it will populate the original language's custom field type values into the translation version boxes. This was really helpful for some post types that essentially had the same information across all languages.

    Can someone help look into this? I also queried Polylang support.

    Hello,

    Thanks for reaching out.

    If you use the code to register the custom post type without using Meta Box, do you see the same issue?

    Please follow the documentation
    https://docs.metabox.io/extensions/mb-custom-post-type/#getting-php-code
    https://developer.wordpress.org/reference/functions/register_post_type/

    Hello, I put in the PHP from Metabox for the CPT into functions.php but the issue persists.

    Does this also mean the CPT needs to be removed from Metabox?

    Hello,

    Yes, if you register the CPT by code, you can remove the CPT from the UI: Meta Box > Post Types page.

    Let me know how it goes.

    OK, I was able to create the custom post type manually, and remove the CPT from Metabox (I tested this by adding/removing the CPT code from functions.php).

    The issue seems like the Custom Fields (created thru MB Custom Fields)related to this CPT post type are not being duplicated anymore for the other languages, but they were before.

    Hello,

    Thank you for the details. I can reproduce the issue on my demo site and I've escalated this to the development team to support duplicating the field value along with the post.

    Hopefully it will be available soon.

    Hello, I just found an additional related issue. I tried to add a new field to the custom fields (file_advanced) and it won't save due to something between Metabox and Polylang.

    Maybe this is related.

    Hello,

    Can you please follow the documentation to set the field group translation to Translate and recheck the issue with the field value when duplicating the post?

    Hi Peter,

    I'm sorry I did not get to this earlier. I tried your suggestion for changing the field group translation to translate, and it now works as expected.

    Thank you!
