Registration web problem

Hi , elitepvpers . I used abrasive registration but this script have old recaptch v1 . I tried to change my key public/private in recaptchalip.config.php but still have same problem .

So if can anyone tell what i have to do or can give me new scripte .
thanx for reading .

you are using old scripts, which do not have all the necessary security, as well as to change captcha not only need to change the public key, you can create a captcha yourself, it does not take much.
