In the stats and analytics the filter date selector is not working. Just in case you didn't know. I know these things take time to correct.
As I said before not working for me on chrome. I do know how the selector works. Been doing it quite a while now.I just tried it on Chrome and it works well. First choose for Custom Range in the date menu and then click on two days and after that on apply. it works in Chrome for me.
