Empty IP adresses

Piwik is not showing IP adresses after last update.

Every single tracking record show only following:
Provider: Unknown

OS/Browser detection looks correct, but empty IP’s leading to failing geolocation.

Did anyone notice the same problem?

edit: it is not caused just by failed update, recently i tried fresh install with empty DB, new tracking codes, … problem still persist


After updating did you remember to copy the geocity dat back?
