Sounds like a problem with CF7 (missing file maybe?). The error message says that one of the classes the CF7 consists of, is not available.

Math Captcha only calls this class – WPCF7_Shortcode – to extend form fields avaiable in Contact Form 7.

Does CF7 work fine on your site? Don’t you get any other error messages?
