Hi everyone,
I migrated my Matomo instance to a new server on 2026-08-25. Afterwards I noticed that the visits, hits, pageview, … figures for that day are far too low. The numbers for the current day are fine again, so it seems to affect only the day of the migration.
What I have tried so far:
./console core:invalidate-report-data --sites=all --dates=2026-08-25
./console core:invalidate-report-data --sites=all --dates=2026-08-25 --segment=""
./console core:archive
The archiving ran through, but the numbers for 2026-08-25 stay just as low as before.
The interesting part: as soon as I apply any segment, the numbers are correct. So the raw tracking data seems to be complete and only the default segment (“All Visits”) returns the wrong values. That makes me think the pre-archived “All Visits” reports are somehow not being rebuilt, while segment archives are generated on the fly and therefore show the real data.
Has anyone seen this before, or has an idea what could cause it?
Additional info:
- Matomo version: 5.13.0
- archiving via cron
