Menu don't works on mobile

Hello,

my site is www.zingegneria.it
I don’t know what is the reason.

Thanks to those who will help me

Hello there,

I am inspecting your site; from the web browser, it is displaying a line of JS error and it is indicating that cache plugin could be the source of the problem. Please try to temporarily disable code optimization. If it remains the same, try disabling the cache plugin.

Let me know how it goes.

I have disable autoptimize and then menu works fine also in mobile device.
Thank you very much.
You know if there is an autoptimize like plugin that could work without menu problem ?
Thank you again.
