I have a piwik running on a website since 2 month. First all was running fine but now I suddenly realized that there is no data any more since the 15th of march.
All tracking code is correct but even if I call the image tracking image URL in the browser nothing is tracked.
I set debug to true and first thing I realized is, that the tracking image URL has no parameter &rec=1 so the debugger says “GET parameter rec not found in URL, request excluded”, but in the tracking code displayed in the piwik backend there is no rec parameter appended, only idsite=1
When I add the rec parameter in the URL I get an error saying something like:
Error query: SQLSTATE: Integrity constraint violation: 1062 Duplicate entry '39587' for key 1 In query: INSERT INTO piwik_log_visit ...
I checked the databse with phpmyadmin, it seems to be ok.
Any ideas what I could try or what might have happened?
