I have a problem with captcha on my website. When I want to ask question about product, captcha is not showing and after asking it writes message "Code is not valid". I've been searching for solution for last 2 days and I found nothing that helped me.
My website: URL
website is in czech language, so you are looking for button "zeptejte se na produkt" (orange button right under 2-3 Days image)
Thanks for any help.
