BuddyPress.org

On my multiuser site Streams etc. are there but I’m getting all sorts of errors due to links pointing to incorrect pages.

My site is at retrofitdiairies.org

For instance a buddypress profile points to http://user.retrofitdiaries.org/members/user/

Instead of as it should be: http://retrofitdiaries.org/members/user/

What can explain this? Was all working fine prior to upgrade to 1.5

Thanks
