I want to add the standard captcha from Magento to our customer registration page. Now I saw that you can enable this captcha in the configuration (System -> Configuration -> Customer Configuration -> CAPTCHA -> Enable Captcha on Front-end). But when I do that and I go to the registration page, there is still no captcha. But when I click on the registration button I get the message:
Incorrect CAPTCHA.
Is there somewhere a tutorial or something? Because I only found it for the contact page and nothing for the registration page.
Thanks for your time.
