I am importing old statistics from the beginning of 2010 to the end of September 2011 on a brand new Piwik install.
I am using setForceVisitDateTime() to force the visit date.
I see new additions to piwik_log_link_visit_action and piwik_log_visit as the entries are added.
However, after having imported the statistics, I can’t get it to show up on the overview pages (which I think you call “reports”.)
For example, if I pick year, 2010 is not available (even though there are hits in that year.)
If I manipulate the URL to show 2010, I get 0 visits. However if I go to the visitor log I can see the visits from 2010 just fine.
Please let me know how to resolve this!
