Your site will not even come up for me and I think you are probably fighting a losing battle but try this if you are using a version other than mine;

In file /core/lib/recaptcha/recpathalib.php find line 40, it should be;

define("RECAPTCHA_VERIFY_SERVER", "api-verify.recaptcha.net");

and change it to;

define("RECAPTCHA_VERIFY_SERVER", gethostbyname('api-verify.recaptcha.net'));

I also cannot access your site. It reports the following errors:

Warning: realpath() [function.realpath]: open_basedir restriction in effect. File(/usr/local/apache/htdocs) is not within the allowed path(s): (/home/:/usr/lib/php:/tmp) in /home/a1735481/public_html/vam/captcha/simple-php-captcha.php on line 75

One of the many reasons NOT to use free hosting :rolleyes:
