OS: Debian 10.3 ISPConfig: 3.1.15p3 (multi server) All systems installed about 90 days ago, works as expected - except database size and quota. The used database space (MariaDB) is not displayed (monitored), neither by the master nor by the slave server in -> Websites -> Database quota. This applies to (loged in) customers (see the attached image  ) and admins (see the attached image  ). It works perfect only on the main Admin Dashboard (see the attached image  ). In this case the database names are also displayed correctly (uppercase db names used). Please compare the name of the test database i created. Can someone confirm this strange behavior? Some ideas for a solution? Bug?
