[Issue] on recaptcha enabled

[isnuryusuf]

on file execute.php

the code: $captcha = new Captcha($config['captcha']['type']);

should be: $captcha = new Captcha($config['captcha']);

on config.php, we should enable url: $config['captcha']['url'] = 'https://www.google.com/recaptcha/api/siteverify';
