I tried to upgrade from 1.11.1 to 2.1 but failed with the following errors, retried several times, database seems to be ok (site webtermine.at is up with no issues) - please help, thx!
There is an error. Please report the message (Piwik 2.1.0) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).
