@dahliaa I can see a lot of JS errors in the dev console. It could be something to do with the JS plugin that you’re using for navigation specifically this line in your JS file:
TypeError: Cannot read property 'classList' of undefined
at n (layout.theme.js?v=10508201567535050176:formatted:792)
line 792 is:
line 791>>> var e = t.querySelectorAll(".js-link");
line 792>>> t.querySelectorAll(".sub-open")[0].classList.remove("sub-open");
