Уважаемые форумчане! Начиная с декабря 18 года ранее работающая kcaptcha выдает ошибку:
PHP Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; KCAPTCHA has a deprecated constructor in .../public_html/mailsender/kcaptcha.php on line 19
Пожалуйста помогите исправить код так, чтобы в будущих версиях php ошибок не было.
