No visible databases are connected to the database server, still it cannot be deleted.
How can I find out which databases oder users prevent the deletion?
How do you try to remove the database server and have you stopped the service before trying to remove files? If the service is still running, it might not be possible to deinstall.
In the database overview it says 0 databases are on that server.
When I mark it and click on remove it claims databases or users are still on that server, but I cannot see those in Plesk, so I cannot delete them (if they exist at all)...
