Errors after upgrading to Piwik 3.0.0-beta1

After upgrading to Piwik 3.0.0-beta1 I have a lot of warnings from PrivacyManager on the dashboard.
This is with the PrivacyManager plugin disabled.

On system check everything is green but it looks like there is alot of files under file integrity that’s different. Have tried to delete all the files and copy them over again.

Running Windows Server 2008 R2 (7601 SP1)
MySQL: 5.7.11
PHP: 5.6.26
IIS: 7.5.7600.16385

If I try to enable the plugin and navigate to /index.php?module=PrivacyManager…etc I get this error.
Error in Piwik: Key "delete_logs_enable" for array with keys "delete_logs_enable, delete_logs_schedule_lowest_interval, delete_logs_older_than, delete_logs_max_rows_per_query, enable_auto_database_size_estimate, delete_reports_enable, delete_reports_older_than, delete_reports_keep_basic_metrics, delete_reports_keep_day_reports, delete_reports_keep_week_reports, delete_reports_keep_month_reports, delete_reports_keep_year_reports, delete_reports_keep_range_reports, delete_reports_keep_segment_reports" does not exist in "@PrivacyManager/privacySettings.twig" at line 91

Got it working by setting wincache.ocenabled in php.ini from 1 to 0
