After the upgrade,the first page of the statistics, get this error.
I tried to delete all the folders in the directory “\tmp\templates_c”, but I have not solved.
There is an error. Please report the message (Piwik 2.0.3) and full backtrace in the Piwik forums (please do a Search first as it might have been reported already!).
