I have used "MB ACF Migration" to migrate a custom post from ACF to Metabox.
All post and taxanomies are migrated successfully.
The problem is that the categories are not showing in the WordPress "Add new" and "Edit" screen so I can't use them. But they appear everywhere else. Frontend, as admin columns and in the WordPress menu. But not in the "Add new" and "Edit" screen.
Enable the option "Show on edit page" fixed the display issue. However, I'm not able to update the custom post if the taxonomies are enebled. I get this error message:
Fatal error: Uncaught Error: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function "" not found or invalid function name
in /var/www/tocn.totalweb.dev/htdocs/wp-admin/includes/post.php on line 444
