It looks like load the very long page content, duplicated
I tried to change to safe-mode, and find this error on console:

Have you tried a `./launcher rebuild app` to see if that helps?

It does not work when I rebuild app.
I tried to restore last backup, but it seems keeping display errors.

Having a search, a similar error was noted in this topic [Service-worker redirection 403](https://meta.discourse.org/t/service-worker-redirection-403/224096) which was related to a misconfigured CDN, if that helps at all?

I have cloudflare, but not use in proxy.
That means web still run server ip directly when it has errors.

I found problem, it caused by multilingual plugin:
[https://github.com/paviliondev/discourse-multilingual.git](https://github.com/paviliondev/discourse-multilingual.git)
It will be ok if this plugin disabled.
