Yesterday since the 2.12.0 update piwik is not tracking all the visits to sites. I’m comparing 4 sites which track statistics in piwik vs two similar web stats services. My numbers are always more or less consistent, but since Piwik last update, it seems that only HALF of the entire visitors are being tracked.
Today I’m experiencing the same issues. I compared mentioned 4 sites to check if it was a “local” issue of one domain / site, but I think Piwik is failing to record visitors.
Thanks in advance for your support!
