Hey guys,

I have upgraded my captcha, and it stops working for account creation. It doesn't submit the form and keeps saying this on the top of the page when hit submit:
"NOTE: If you already have an account with us, please login at the login page."

This affects both my contact page and create account page:
http://www.simpleartsplanet.com/contact-us
http://www.simpleartsplanet.com/create-account

I looked at the log and found this entry:

PHP Code:
PHP Warning:  implode(): Invalid arguments passed in /public_html/includes/classes/observers/google/ReCaptcha/Response.php on line 128 
Can someone help take a look?

Thanks,
Lis
