Datepicker fallback doesn't work

Can I see the site?

Yes of course.
Here’s the page with the form.

Maybe it depends by the theme I’m using (Bridge by Qodeinteractive)?

Thanks!

Ok, I definitely think the problem it’s the theme I’m using.

I tried switching to Twenty Fifteen and it works perfectly.

It doesn’t work with Twenty Fourteen and Twenty Thirteen though.

Hope this can help…

Thank you again

I’ve found a solution.

It was a CSS issue.
JQuery UI was loading but hiding behind other elements.

Fixed this with this line of CSS:
.ui-datepicker { z-index:9999!important }

Thank you
