Heartbeat and ISpConfig 3 cluster

[till]

The above error is not related to creating a client in ispconfig. The query is from a ispconfig update were the ispconfig datannbase must have been updated or manually replaced before so that the updater could not recognize its structure due to a missing db version number in the server table of this server. So it is something related to your initial setup, maybe you installed ispconfig more then once on the server without removing it completely before.

You can e.g. try to skip this replication step in mysql.
