I tryed this code but the german version is not working (italian is ok)
$lang = substr( get_locale(), 0, 2 );
global $post;
if ('it' != $lang ) {
$term_name = get_the_terms(get_the_ID(), 'intro_'.$lang)[0]->name;
} else
$term_name = get_the_terms (get_the_ID(), 'intro')[0]->name;
the line with 'intro_'.$lang
breaks the posts layout, any solution?
