Hello,
Thanks for the details!
I just ran some test, and it works fine on my end. Here is the video of my test.
Can you try to setup a simple test like I did in my video, see if you get the same result? Here the my Field Group Json Export. You can save that json into a file, and import it from the “ACF > Tools” admin menu.
The Field Group is called “My Taxonomy Terms” and will be displayed on any Post Type: Page in your WP Admin. The Taxonomy Terms field will only display the “Category” Taxonomy.
Try to select a Category, and run get_field('my_taxonomy_terms', 15);
(where 15
is the post id of your test page). You should get the same result as in my video.
If the issue is still there, then it probably means you have some custom code/hook either in a third party plugin or in your theme which break the feature.
In order to isolate the problem, I would recommend clone your website on a development / staging environment using Duplicator, or with your hosting backup solution. Then try to disable all your plugins one-by-one (at the exception of ACF Pro & ACF Extended) until you find which one cause the issue.
If the problem persists, try switch to the native WP Twenty Twenty Two theme, to make sure you don’t have any custom code in your theme which would break the field.
In all cases you should be able to confirm it works like I did, by setting up a clean WP install with ACF Pro + ACF Extended only.
You can read more about how to setup a favorable environment for debugging WordPress & ACF in our guide here.
Let me know if you found something!
Thanks!
Regards.
