I got almost empty page when tried to open api documentation intervals.icu/api-docs.html
That’s how page looks
I found this error in console logs:
Mixed Content: The page at 'https://intervals.icu/api-docs.html' was loaded over HTTPS, but requested an insecure script 'http://unpkg.com/rapidoc@9.3.8/dist/rapidoc-min.js'. This request has been blocked; the content must be served over HTTPS.
works now… (it showed that page for like 2s then it loaded the right onw)
still doesn’t work for me
I get the same page as you. The links to the relevant posts are there, one before the comma, one after and one after the ‘and’, but they are not visible. Looks like white text on white background 
. You can hover and click, in my case, to take you to the forum post.
now it works for me. Looks like it was the issue with call to https://unpkg.com/rapidoc/dist/rapidoc-min.js and somehow it was fixed on their side
