Почему это не воркает?

короче если строка так - <div class="g-recaptcha" data-sitekey="<?php echo pun_htmlspecialchars($site_key) ?>"></div> , то пишет неверный домен ключа recaptcha, а если так
<div class="g-recaptcha" data-sitekey="site_key"></div>, то выводит галочку, но не логинит и пишет что неудалось пройти капчу
