[wp-forums] Menu not showing on mobile-tablet

[Daniele Bruccoleri]

Hi everibody, it's Daniele from Italy.

I have a problem with my wordpress site www.greciaviaggipassione.com. 

The site has been developed using 80 days theme. The problem is that the
main menu is not showing on mobile phone and tablet.

I'm new to wordpress and I searched on google a specific solution to this
problem for site developed using 80 days, but I didn't find a specific
answer.

Can anyone help me please?

Daniele
