Сегодня столкнулся с такой-же проблемой, старенький сайт на Joomla 2.5 + JoomShopping 3.16.0 - замучали боты и нужна ReCaptcha v2
Первое что нужно сделать для установки CAPTCHA v2 для JoomShopping - это выкачать у них плагин:
в моем случае это был Registration captcha 1.0.1, устанавливаем и делаем настройки по инструкции на этой же странице..)
Далее меняем содержимое файла plugins\captcha\recaptcha\recaptcha.php на следующее:
