Business Portfolio Conflicts with BuddyPress Can't Start New Topic

I have been having a problem since I upgraded both Wordpress (3.3.1) and BuddyPress (1.5.3.1)

I am using the Business Portfolio Child theme (Business Portfolio Version 2.1.23), with Membership and BuddyPress plugins, but since the upgrade it is not possible to create a New Topic in BuddyPress forums.

If I switch themes the problem goes away.

Any fix for this or do I have to change themes?

Thanks,

JoAnn
