There's a lot of JS and ajax and extra scripts and things (far as I can tell at a first look) on this website, some of which don't even seem to serve any purpose. If you look in the source (via Inspect Element, not actually viewing the page source, cuz of the ajax and crap -- if you try to reload the page, for example, you get a 404; the history is intact though), you'll see there's an extra menu as well, first thing in the body (ul.onepage-pagination) that's invisible, but I don't see any styles that should be rendering it as not visible or not displaying. There's no text wrapped by the a elements within the list items, so it could just be that, but when I edit it in DevTools and add text in the links it still doesn't appear.

But my main issue is that the navbar that does display (bootstrap-based), is invisible on mobile devices -- not when you shrink the screen to mobile size, but only when viewed on an actual tablet or phone. Can anyone tell me why that is? Perhaps it's the bootstrap JS trying to shrink it to the dropdown menu for mobile, without that intact, but then that should happen when you shrink the window as it normally does in bootstrap, based on viewport size.

Please help me figure out how I can figure this out. I have the user-agent switcher Chrome extension but that doesn't seem to do anything for me, plus when I try on the site in question it reloads the page which returns a 404 error because when you load the site the ajax appends /home or whatever other "page"-part you're on to the URL, which isn't a real location.

Any insight would be greatly appreciated, thank you.

Useful debugging notes and a focused checklist based on ’s observations (hidden extra menu, SPA pushState that makes reloads return 404, navbar visible when resizing desktop but not on a real device).

Common reasons the desktop-resize case differs from a real phone/tablet

  • The site may be checking device characteristics other than viewport width (UA sniffing, touch-capability checks, or server-side device CSS delivery).
  • Media queries using device-width (or other device-specific checks) behave differently than max-width.
  • JS that runs only on touch devices (adds classes, hides elements, or fails with an error) can remove or move the Bootstrap navbar.
  • Positioning quirks: transforms on an ancestor can break position:fixed on mobile, making the navbar appear “gone” even though it’s present.
  • Single-page app behavior (pushState) causes 404s when reloading deep-linked URLs — that complicates testing unless the root URL is used.

Practical reproduce-and-debug checklist

  • Use Chrome DevTools Device Mode (Toggle device toolbar) and reload the page while emulation is active so the server and scripts see the mobile UA/DPR/touch. For SPA sites, load the root URL (/) with emulation active, then navigate inside the app to avoid 404s.
  • Use remote device inspection for real-device logs (chrome://inspect for Android, Safari Web Inspector for iOS) to see console errors and the live DOM/Computed styles.
  • Inspect the element’s computed style on a real device: display, visibility, opacity, transform, z-index, and whether a mobile-only class was added.

Quick checks to run in the console

'ontouchstart' in window     // true on touch-capable browsers

And examine CSS for queries like:

@media (max-device-width: 480px) { ... }   /* avoid this */
@media (max-width: 480px) { ... }         /* prefer this */

Priority items: look for console errors preventing Bootstrap’s collapse script, confirm jQuery/bootstrap.js load order, search for touch-detection code that adds/removes classes, and check for transforms on ancestors of the navbar. These steps isolate whether the problem is CSS-only, server-side UA handling, or JS-driven.
