Today I’ve upgraded my Piwik from 2.2.2 to 2.3.0 using “Update Automatically” method. The upgrade process
was successful, but something has been broken, because I couldn’t see any data. Please take a look at the attachment
with a screenshot. There are PHP syntax error and the missing files.
Can you have any idea what a reason of the issue could be?
PS. I’ve downgraded my Piwik to 2.2.2, because I need a well working production server.
