While trying to upgrade from 1.12 to 2.1.0 I got the following error message
Fatal error: Interface ‘Piwik\View\ViewInterface’ not found in /var/www/tilastot.verkkonummi.fi/core/View.php on line 107
It looke like the upgrade was interrupted, reloading the page did not help. As far as I know, the file privileges were correct (same user as apache2 user, ie www-data, temporiraly. I do harden the permissions in production use.)
Piwik did not let me sign in after this . I was forced to revert to backup of 1.12.
Anything I can do?
If this is connected to xcache, please note that the server needs opcode caching.
Here you have the server info:

I would like to upgrade, but currently it looks difficult.
