ISPConfig 3.1.15p2 Ubuntu 18.04.3 LTS MySQL 5.7 I am in a multiserver environment with a mirror server of web, ns, mail server) including master to master DB replication. ISPConfig is located in DB Servers. Error Received: [INTERFACE]: Falsche Anfrage / Wrong QuerySQL-Query = SELECT * FROM `mail_relay` WHERE server_id = 9 -> 1146 (Table 'dbispconfig.mail_relay' doesn't exist)
Have you looked in the database, does that table exist or is it really missing? Have you run the repair tables and check tables operatations?
I guess you used the resync function in ISPConfig? Seems as if the table is referenced there by error.
I did not say that you changed something. I said that the table is referenced by the resync function in ISPConfig by error.
