Update from 1.11 to 2.0: 1146 table missing (1 reply)

Just upgrading and following message is shown:

---------
/var/www/hp/piwik/core/Updates/2.0-a7.php:
Error trying to execute the query 'ALTER TABLE piwik_logger_message ADD COLUMN tag VARCHAR(50) NULL AFTER idlogger_message'.
The error was: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'db.piwik_logger_message' doesn't exist
----------

An SQL-command would help ;)
Like last time. [forum.piwik.org]

Thank you and winterly greetings
