I use Zen Cart 1.3.8.
I installed Google reCaptcha and I followed the instructions.
I used your form
Code:
create_account.php
(from "pre-v1.5.1).

I read:
Code:
$ zco_notifier-> notify ('NOTIFY_CREATE_ACCOUNT_CAPTCHA_CHECK');
and after
Code:
if ($ error == true) {
This also happens through Contact Us form

What's wrong?
