Убедитесь, что у вас есть:

1. Создать папку captcha для root с разрешением 777
2. В config.php $config['base_url'] = 'http://localhost/yourproject/';

Создайте папку вне приложения под названием captcha Captcha Helper. Думаю, вам также нужно иметь больше $ vals, а не только img_path и img_url

Также убедитесь, что права доступа к файлам chmod 0777 или 0700

Возможно, вам придется настроить некоторые маршруты

 $route['register/generate_captcha'] = 'register/generate_captcha';
