BuddyPress.org

ok,here are my thoughts and I will like to go into more details,so would love to hear from everyone of you who has / or is facing this issue.

1.De activate buddypress/buddypress dependent plugin

2.Upgrade buddypress

3.activate it sitewide .

I hope,if you de activated it before upgrading,activation will not generate error,as I have tried on 3 different installs,and I believe the root cause of the error is the sitewide activated plugin upgrade mechanism.

So,It will help everyone ,if the people who go through this ,post their experiences here.May be it can help in investigating further the causes.
