If you look at your javascript console (F12 on many browsers), you’ll see
categories:25 Refused to load the script 'https://asiavaper.com/assets/locales/en_US-13bd90597606fb9c418137d59bfbf2505d12db86463283f82980508460bbb766.js' because it violates the following Content Security Policy directive: "script-src 'unsafe-eval' 'report-sample' https://asiavaper.com/logs/ https://asiavaper.com/sidekiq/ https://asiavaper.com/mini-profiler-resources/ https://discourse.sgp1.cdn.digitaloceanspaces.com/assets/ https://discourse.sgp1.cdn.digitaloceanspaces.com/brotli_asset/ https://asiavaper.com/extra-locales/ https://asiavaper.com/highlight-js/ https://asiavaper.com/javascripts/ https://asiavaper.com/plugins/ https://asiavaper.com/theme-javascripts/ https://asiavaper.com/svg-sprite/". Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.
I don’t know why stuff is linking to that Spaces CDN, but that’s likely the problem.
You just cloned discourse and ran ./discourse-setup?
