I just updated my piwik to the latest version and realised that tracking for all my sites has stopped on Oct 6. The tracked sites are running wordpress or joomla, but all have stopped tracking at the same time.
[li] cleared the piwik/tmp folder
[/li][li] cleared the browser cache
[/li][li] accessed several sites with different browsers to trigger live tracking, no reaction
[/li][li] deleted the piwik_archive_* tables for October (but triggering the recheck did not work out, so now I don’t have any data for October)
[/li][li] ran the system-check (good except for LOAD DATA INFILE)
I am not aware of anything special that I did to any system on Oct 5 or 6. Any ideas?
