Well this was unexpected. Troubleshooting another problem, I decided to upgrade Matomo to the latest beta. It's not a huge installation, so I used update option inside the dashboard. Everything went smoothly, until I logged back in. Now all sites show "No data has been recorded yet".

At first I thought data was wiped. So I went through the database and it does appear data is in the database, but for some reason Matomo isn't recognizing it anymore. The table prefix is correct in the config file, piwik_

It's only tracking data that's not showing up. Websites are still listed, settings are being saved, etc.

I tried running CLI command to reprocess data, that didn't help.

Few details:

• We only import logs into Matomo. No client-side tracking.
• All system checks are good
• PHP 7.2.14
• MariaDB 10.3.12

This is a list of plugins we've deactivated:

Here's a screenshot of what I'm seeing in database:

Any ideas?
