It doesn't work without javascript. And it does work on FF and Tor browser.
But I do get reports that some people on some connections can't get it to work (i.e. if you switch from wifi to mobile it might start working). Looking for the cause.

Interesting. I'll investigate if any other browser "hardening" settings are breaking it. But enabling javascript should be sufficient.
FF displays a very broken site (probably not typical). Tor browser (default config, javascript enabled) looks ok, but returns an error when trying to search.
This is on windows desktop, conected via ethernet.
Ok, an extension was blocking the javascript (on top of noscript). Now it's working. My bad.
