[xwiki-users] Statistics still not working in 2.0.3 ?

Hello, I upgraded my wiki (webapp and xar) from 2.0.RC1 to 2.0.3. While statistics are supposed to work (they were in RC1) as a bug was solved, it seems in fact in 2.0.3 my statistics tables are not updated anymore. I did not change the xwiki.cfg so they should be activated as they used to. I checked the list of plugins which seems ok. There is no exception related to statistics in my logs. Am I missing something ? Thanks, Jeremie
