Yes,I check it again. It's worked since 10.19 until now. But 10.1~10.18 have no data. I also don't know why and how. maybe some developer fix it. Anyway, Thank you for your answer.
as I know not person will change this code....I only see data in 9.24~9.30(We put this function since 9.24)~ Oct 's data became something wrong. And browser tools not show any numbers.
