Milti-language tutorial fail

Dear everyone, I have been trying to make this tutorial work but it won't work at all. This is the tutorial: https://medium.com/@hardluckcreative/making-better-multi-language-squarespace-sites-e46d24094a7d

When I hide the header the links for languages show up, otherwise it just shows up while loading.

Thank you,

I see you used WeGlot and already works here, you try checking it again.
