[Theme: Minimatica] Disappearing Menu

Hi there,

I’ve been using Minimatica as my theme for a few months now, and without messing or touching it, the menu will occasionally disappear completely. I don’t change anything, and it will be gone. I’ve tried creating another menu, but that won’t show either.

My website is http://www.sarahvance.net

Any help would be much appreciated.
