I have version 1.5.5b I installed it and it seemed to be working for the Create Account page.
I did not install it for Contact us as we have that page turned off and only give a phone number.
The next day I checked and many accounts were still being created..
The reCaptcha area is working in talking to Google but is not functioning with the Create Account Button.
So I added: $zco_notifier->notify('NOTIFY_CREATE_ACCOUNT_CAPTCHA_CHECK');
to the /includes/modules/classic/create_account.php per instructions for version 1.5.1 4c:
So now it will say that the reCAPTCHA is not checked which is good, but when you do have it checked It will not create the account.
It just reloads the create account page, it acts like it is successful but I checked in PHP and the account is not being created.
So in the create_account.php file is there another piece of code I need to put in for it to finish creating the account.
