I've just installed recaptcha module and it works fine but I get this error only at the sign up screen (registration screen).

Does anyone know what can I do to fix it??

The error:

Notice: Undefined index: form_id in _captcha_get_posted_captcha_info() (line 604 of /var/www/drupal/sites/all/modules/captcha/captcha.module). Notice: Undefined index: captcha_info in _captcha_get_posted_captcha_info() (line 607 of /var/www/drupal/sites/all/modules/captcha/captcha.module).

check if you have installed the latest module(7.x-2.2) and selected the reCaptchas challenge type dropdowns(for the required pages).. I too had error in displaying reCaptchas..Later i figured that i installed old versions.
