Anmeldedaten oder Verbindungsparameter falsch nach Serverupdate auf 3.0

Hallo,
nach einem Update des j-lawyer-Servers (auf einem Ubuntu-Server-OS) von 2.6.1 auf 3.0 funktioniert die Anmeldung nicht mehr. Sobald ich downgrade (von 3.0 auf 2.6.1.) und die Datenbank „aktiviere“, dh mysql -u root -p; use jlawyerdb; show tables; und quit; eintippe funktioniert es wieder.

In der Server.log erhalte ich folgenden Hinweis:

Kann mir jemand bei dem Fehler helfen? Vielen Dank!
