Captcha not Working

I am using the plugin Captcha on Login and is works on my admin but it does not work at /wp-login.php?action=register and this is theme related as it works which i change to a different theme - any help please


I installed the plugin to try it out but it uses a lot of deprecated code. These errors are visible when the debug mode is on. As there is no point for me to fix incompatibility with a plugin which uses code deprecated in WP 2.0, I suggest you find a different plugin. Sorry.
