you removed the captcha validation, but the Like Entry for the security question was using the captcha session:
$WAFV_Errors .= WAValidateLE((strtolower(isset($_POST["Extras_group_Security_Question_2"])?$_POST["Extras_group_Security_Question_2"]:"")) . "",((isset($_SESSION["captcha_Extras_group_Security_Question_2"]))?strtolower($_SESSION["captcha_Extras_group_Security_Question_2"]):"") . "",true,13);
I changed that to use the random_answer session instead:
$WAFV_Errors .= WAValidateLE((strtolower(isset($_POST["Extras_group_Security_Question_2"])?$_POST["Extras_group_Security_Question_2"]:"")) . "",((isset($_SESSION["random_answer"]))?strtolower($_SESSION["random_answer"]):"") . "",true,13);
