Is anyone also having stats problems?

Hi everyone, my blog stat has been stuck for 2 days (I use WordPress.com Stats 1.1.1), my stats graph has not moved at all, it shows zero from 15th Sep. And my referrers list , top posts, clicks are all empty.

I know that there are still people come and visit my blog these 2 days, ’cause I still receive new comments from different people these 2 days, and I can see there are visits from my “FeedStats” plugin. So there must be a problem with my blog stats.

Please help, any advice would be appreciated! My blog is https://dcimumu.com/iwrite
