PI themes contact form goes with google recaptcha by default. We added captcha to contact form only (footer form has no captcha), because we think that it would look weird in footer.
CAPTCHA WON'T WORK BEFORE YOU OBTAIN YOUR OWN API KEYS!
To stop using captcha please set variable $use_captcha to "false" in handlers\formContact.php and remove peace of code below from contact page html.
