Why doesn't the successful send work?

Question

JavaScript

There is a site on opencart
there is a form Module Form Designer Opencart 3.0, in general, it doesn’t matter
in the Russian version if you fill in the fields, successful sending works
in the Ukrainian version, I generally poke the button, no reaction
Who understands js well, tell me where to dig

Answer 1

If you go to the Network, then the form sends everything. It's just that the form is not cleaned and that's it.
