Ninh-

I’ve looked at your site and of course cannot duplicate the problem without logging in. But, that’s okay.

You mention that you’re using a custom theme. Read the first post in this thread, paying close attention to the parts that talk about custom themes. Also, there are more posts within this thread that discuss theme issues that could apply.

It appears that you are still using BuddyPress 1.0_RC1. I cannot remember if any of these issues apply to RC1. Perhaps someone with longer BP experience can chime in.
