I have extended profile fields defined for my BP installation on http://svn.amebylon.net
Since my last BP Social theme upgrade the first extended field (listed as Primary in the Dashboard and named “First and Last Name (required)” is not saved when you register as a new member. The other fields (City, State, Country) are saved as before.
Please let me know if anything changed in the latest theme upgrade that could explain this behavior.
Installation has WordPress 3.2.1, BuddyPress 1.5.1., and BP Social Theme 1.2.9.
