Report page got php error trunk #3107

My revision is 6206. I update new code from SVN server and can not access Visitor overview page.

The error detail is:

Date format must be: YYYY-MM-DD, or 'today' or 'yesterday' or any keyword supported by the strtotime function (see http://php.net/strtotime for more information)

Backtrace:

fixed in SVN AFAIK

I update latest revision is 6211 but the bug still happen. You can see it here (it is public)

http://www.chuongduong.net/tracking/index.php?module=CoreHome&action=index&idSite=1&period=range&date=last7#module=Dashboard&action=embeddedIndex&idSite=1&period=range&date=last7&idDashboard=1

I think the problem is parameter date=last7.

This link is error: http://www.chuongduong.net/tracking/index.php?module=CoreHome&action=index&idSite=1&period=range&date=last7#module=VisitsSummary&action=index&idSite=1&period=range&date=last7&idDashboard=1

But this one is work well: http://www.chuongduong.net/tracking/index.php?module=CoreHome&action=index&idSite=1&period=range&date=2012-04-12,2012-04-18#module=VisitsSummary&action=index&idSite=1&period=range&date=2012-04-12,2012-04-18&idDashboard=1

(In [6217]) Refs #5473, #3107, fix issue of failure in purged report message logic when special date range (lastN, etc.) is used.

Thank You, it is working well.

(In [refs #3227, #3107, #3201 changed phpunit test according to changes in 6659)
