As far as I know, I've only had this issue come from wolframalpha.com e.g. https://www.wolframalpha.com/input/?i=Factor%5Bx%5E2++-+++16%5D
My goal is to get html using javascript. So opening the developer tools I wrote
document.body.innerHTML;
But get Uh oh! Wolfram|Alpha doesn&#x27;t run without JavaScript.</span></span><div class=\"HHXp5 _2CYJA\"><span>Please enable JavaScript.
, as PART of the response and not the full contents of the webpage.
I didn't want to make assumptions about how the website is operating, so I am going off with the information I got back and framed my question this way. Javascript is clearly enabled and I am guessing some js functionality is redirected prior to the page loading.
I've tried this with the latest chrome incognito and safari.
Taking the suggestions from the comments, the issue was resolved after reenabling javascript on my site settings.
