Reviews
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
