Meta Box

There are 2 things in you code:

1. get_the_post_thumbnail needs the 1st param as the post ID. You can pass $post_id to the function, or simply null.
2. The taxonomy field doesn't save value into post meta. Instead, it set post terms. So you need function get_the_terms to get them.

Here is the working code: https://pastebin.com/txqnp0A3

Does this belong to the post type object itself? I think it's easy to do it with the remove_post_type_support function (https://developer.wordpress.org/reference/functions/remove_post_type_support/).

I mean the version of the Meta Box plugin, not the extension. Can you check it? Is it 4.10.4?

Can you please post your full code here? I tried with your code above and it still works for me. I guess there's a conflict somewhere that breaks the JavaScript (you might want to check the console, too).

Glad that it works for you :). How about the update? Does it work?

Hi ismail,

Currently the plugin hasn't supported that location yet. We will working on that soon.

TGMA will install the extensions as separated plugins and then they have to work as normal install. Have you refresh the admin page after install and activate the extensions from TGMA page? I've just tried again with TGMA and it works for me.

The admin columns also works :(. Can you make a screenshot or short video?

I got it. Looks like the ID of the English version is not translated into the ID of the German version. I got help from WPML team to add this feature in the previous version. I will check it now.

In the worst case, I think a solution for this might be using 2 fields: 1 for English and 1 for German, and in the frontend you can use a condition to get the correct field.
