If you update your site and you see that the site looks the way it should while logged in, but doesn’t look right when you’re logged out, chances are you are using our server caching, but haven’t configured Nginx Helper to purge it.
If you’ve just migrated a site in and you see a vanilla install or if something doesn’t look right, typically this is because the migration plugin wiped out Nginx Helper. It can be reinstalled from the WordPress repository.
If you run into the above two issues, it’s typically that the Nginx Helper hasn’t been configured.
