While testing the Auto-Archiving script just now I noticed that 3 out of the 6 requests made by the script has no user-agent string set; the 3 others are set as “Piwik/1.8.4”. This is not really a problem usually except that I have my web server set up in such a way that all requests with no user-agent set is immediately rejected with a 403.
I hope this can be fixed for a version in the future.
The 3 requests are the ones with period=week, period=month and period=year.
