Hi,
Both of the warnings are about something unrelated.
In the latest Matomo release .lfsconfig has been removed from the build package, so you can now also remove it from your Matomo instance. But the file is completly useless and doesn’t interfer with anything so it can’t cause any issues.
This is just the reminder that you need to setup Geolocation. Otherwise you won’t see accurate location data. (but everything else should still work).
So the easiest way to check why no data ends up in Matomo is to open your website in the browser, open the developer tools and check for errors and check if the requests to piwik.js and piwik.php are successful.
