Why is my mobile hamburger menu not visible?

[OurFamilySell]

As the subject says, my hamburger menu has went missing. I've tried turning off all apps I've recently installed as well as tried installing code from other similar questions I've come across. 

The "collection" on the floating menu is also missing.

Help would be greatly appreciated.

Hamburger menus are not meant to be displayed on desktop and laptop. It's visible on mobile devices, but doesn't work.

I checked on my Samsung Fold 4 and am iPhone 12 Pro and the menu isn't showing up in any of them.
