re Captcha module does not show up..

[DuckIT]

Hello,

 

I bought this re Captcha module:

 

http://addons.prestashop.com/de/18478-re-captcha.html (v1.0.4-recaptcha)

 

It looked easy to install with the short youtube-video but it is not visible at our contact page. We are useing Prestashop version 1.6.1.4.

I registered at google for the keys, filled in the line to our template and installed the module himself, too.

Is there anything special I have to look for?

 

Cache is cleared.

 

Thanks,

 

Philipp
