Missing data from daily visitors overview


We are missing history data when accessing daily Visitors Overview from 12th April till 26th April.

We don’t know exactly what went wrong, last week we did 2 different things:

  • Installed a custom plugin and we ran the cron:archive shell command to pre-process the report data;
  • Upgraded Piwik to 3.0.3

Only daily overview was affected, for all the other periods (week, month, year) everything shows correctly.
I’ve checked in the database and the daily values are still there and saved.

Is there any way to get the missing data to show in the graphs?

Here is a screenshot from DB that data exists, for example for 20th April:


Any idea?
