After upgrading to wp 3.1 and GAB 2.0.1, the graph on wordpress dashboard, displays a date range that is one month behind the actual period.
The date range displays correctly
ex. 2011-01-25 to 2011-02-24
But the line graph shows a period from
2010-12-26 to about 2011-1-30
BTW I noticed that 2.0.1 fixed some incompatibility issues that I had previously experienced on Hostgator and when I went to the plugin developers website, couldn't find a place to make a quick thank you donation. :)
