在您的functions.php 添加以下代码，摘自Remove "Category:", "Tag:", "Author:" from the_archive_title.

add_filter( \'get_the_archive_title\', function ($title) {

    if ( is_category() ) {

            //being a category your new title should go here
            $title = single_cat_title( \'\', false );

        } elseif ( is_tag() ) {

            $title = single_tag_title( \'\', false );

        } elseif ( is_author() ) {

            $title = \'<span class="vcard">\' . get_the_author() . \'</span>\' ;

        }

    return $title;

});
