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 [3] ) and admins (see the attached image [1] ). It works perfect only on the main Admin Dashboard (see the attached image [2] ). 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?
