固定ページでタクソノミーの一覧を出したい時、カスタム投稿のカスタムタクソノミーも含めて表示したい時はクエリーを上書きするか WP_Queryクラスを利用します。 1ページ目は指定通りに表示されますが２ページ目以降はうまく表示されないことがあるのでそこらへんの問題を解決できそうなヒントになる記事をまとめていきます。

上記の参考URLをもとに必要としてた環境で実装したソースは下記です。 functionsp.php

<?php

    $showitems = ( $range * 2 ) + 1;

    global $paged;
    if ( empty( $paged ) ) {
        $paged = 1;
    }

    $nextpage = $paged + 1;
    $prevpage = $paged - 1;

    if ( $pages == '' ) {
        global $wp_query;
        $pages = $wp_query->max_num_pages;
        if ( ! $pages ) {
            $pages = 1;
        }
    }

    if ( 1 != $pages ) {
        echo "<div class=\"pagination\">";

        if ( $paged > 1 ) {
            echo '<a href="' . get_pagenum_link() . 'page/' . $prevpage . '">前へ</a>';
