I have a site that redirects from http > https. I have read the following info but I am lost on the solution if there is one.
Check that the Piwik domain name in your Javascript tracking code is correct (this URL is in the second line of the Piwik tracking code).
There have been cases of missing referrers when the Piwik JS code in the pages points to a URL that returns a 302 response instead of the final destination. It seems that some webserver compromise the tracking request when such redirects occur. Check in particular if the URL (doesn’t) contains “www.”. Also, if the server does an automatic redirection from http to https which also affects tracking requests to piwik.php, it might create problems such as missing referer data. Make such any http->https redirection excludes piwik.php requests.
Thank you in advance,
Scott
