8}
9

試したこと

①function.phpに「remove_action( 'shutdown', 'wp_ob_end_flush_all', 1 );」を追記しましたが、一部エラー文が消えただけでした。

②以下のの $news と $news_linkのphp文を削除。

front
1            <?php
2            $news = get_term_by('slug', 'news', 'category');
3            $news_link = get_term_link($news, 'category');
4            ?>

⇒正常なページに戻りました。しかしmore部分(aタグ)はマウスポインタが変わるが押しても反応なし

③下記のaタグのみを削除

front
1<a href="<?php echo $news_link; ?>"><p>more</p><img class="next1" src="<?php echo get_template_directory_uri(); ?>/img/preview.png" alt="次へ"></a>

⇒正常なページに戻りました。しかしmoreが削除されホバーしても反応なし。

自己解決

aタグを以下にすることで解決できました！

<a href="<?php echo home_url(); ?>/category/news/">more<img class="next1" src="<?php echo get_template_directory_uri(); ?>/img/preview.png" alt="次へ"></a>

あと投稿時のカテゴリがnewsになっていなかったことも問題だったようです。
