Disable Hamburger Menu on Mobile

Hello,

I am unable to find a way to disable the hamburger menu that appears only in mobile/tablet mode on my site : edithbernier.com

It’s a menu with my links to my pages, and it’s really annoying and useless. It doesn’t appear at all on my desktop browser and I want it that way on all versions.

Thanks for your help!
