I use matomo on-premise, And recently I found a problem. There are some visitor that do not have their first visit data in table matomo_log_vist. all of their visit data show that visitor_returning = 1.
I want to know what’s the reason,and how to fix it?
Here is the example:
Hi @wenjuan_xie
Didn’t you delete some hits, thanks to GDPR tool or with raw log auto cleaning?
GDPR tool
Raw log auto cleaning
Hi @heurteph-ei
I confirm that I have not deleted any historical Matomo data and didn’t make any change with GDPR tool.
Are there any other possible reasons for this result?
Can you check if the visitor has a user ID, and if so, can you check this user ID is not associated with another visitor?
On your last request screenshot, can you include also the visitor_count_visit
column?
Very strange indeed: the first visit of 00074ebec9063ee1
doesn’t appear…
It has been deleted, and I don’t see other reason than:
- Manual deletion in the DB
- Manual deletion through GDPR tool
- Manual / auto deletion via Matomo DB cleaning
