Reset votes counting

Hello,

Thanks a lot for your very precious “thumbs up” plugin I am using on my crowdfunding website :

http://wp.klappagency.com/

I would like to reset manually some of the project votes counting. I saw I needed to update my functions.php file, but I don’t know where precisely…(last time I tried, I broke the all website…).

Please help me on this subject 🙂

Best regards,
Arnaud
