Dear Matomo support,
After upgrading from Matomo 3.13 to 4.5 (on premise), we can login in to the backend but we see no new stats are previewed in the backend. We can’t find any error’s on the server and see the request coming in on the server. The old data is still there.
Matomo-versie: 4.5.0
MySQL-versie: 5.5.68-MariaDB
PHP-versie: 7.3.29
Is this a known issue? I hope someone can help
