Used to like it but not anymore

By ostonegi on March 14, 2025

This plugin used to be good but now they are pushing a "paid security package" and fear mongering. They have added a pretty useless "malware" scan that marks a lot of normal php files used by other known and popular plugins as "suspicious". I understand trying to leverage the financial potential but this way is just lame.

Thank you but no thank you.

休日設定をしても配達希望日として設定できてしまう

By bocchimktg on April 11, 2023

食料品には対応してない印象を受けます。生鮮食品関係のECで無料版を利用していますが、いくら休日期間を設定してもお客側からは配達希望日を設定できてしまいます。商品の消費期限が短く出荷調整などがあるため、こちらで休日とした日はお客側には配達希望日として表示しないようにして頂けると助かります。3年前のフォーラムでも似たような質問(配送に関する新機能希望2020年3月25日)が出ていて機能追加される旨が書いてありましたがプロ版では対応されていますか?

レスポンスも更新もありません → 追記:いただけました

By Takahashi Ei (enjoybeerlife) on June 10, 2022

非常に意義のあるプラグインだと思いますが、更新が継続されていないようで残念です。 --- 追記: 更新再開していただけました。感謝いたします。 いささか身勝手な書き方になってしまって、お詫び申し上げます。 今後とも応援させていただきます。

良いですね。ありがとうございます。

By souichiroukikuchi on March 7, 2021

昨日にインストールして色々と設定を行っています。 WooCommerceを日本の商習慣にローカライズするプラグインで使いやすいです。 ありがとうございます。 1点、不具合(なのかな?) 配達予約可能開始日で当日配送ができる場合は0を入力してください、とあったので0を入力すると、なぜか2で表示されます。 2を入力した時も2で表示されるので見た目からは違いが分かりませんでした。 バージョンは2.2.12 WPのバージョンは5.6.2 です。

Paypalチェックアウトがどうしてもエラーになる

By skyies618 on July 28, 2020

サンドボックス上でなのですが、Paypalチェックアウトを使いたくても、どうしても「よみがなと郵便番号を記入せよ」とエラーになってチェックアウトでの支払ができません。 通常のPaypal支払は可能なのですが……。せっかく対応を公言しているのに使えないのは残念です。 日本ではPayPal普及率が高くないようなので、使えなくてもいいということにしたいと思います。 WooCommerceは使いやすいプラグインなので、日本語対応してもらえるのは大変助かっています。
