I am having this same problem. I know a plugin is causing the issue (gtranslate) but it is essential for my website. But when I switch the language in my website the form doesn’t work anymore .. it does work when the website is not translated. Is there a way we can fix it, please?
I did find a workaround.. when I turn off AJAX it works. Only thing is that if I click to the next page in my form. The page scrolls down too far. So the user will have to scroll up again to continue with it. Is there anything I can do about that. (as a plan B)?
