Jragoon Hi! I currently can't reproduce this with NoScript in Chrome or Firefox, on Arch.
If you note your URL bar, you are still on https://kagi.com/search, which still has scripts & different server logic.
The way our no-js support works, is we have a
<noscript> tag that will redirect you to https://kagi.com/html/search, which has different logic and content to support this.
It would appear somehow your browser did not act on the
<noscript> tag to load the apropriate version of the site.
Could you try navigating around to, say the homepage, and trying again? Or give another browser a try?
