Re: custom profile data not getting saved in BP 1.1.2
Check the codex for how to upgrade your BP theme from the 1.0 method to the 1.1 method. It’s actually easy, but just takes care following the directions. I’m not replying from my dev machine so I can’t browse through the sources easy at the moment, but try upgrading your theme to the 1.1 architecture at least and see if that brings you any success.
Otherwise there might be some deprecation getting in the way somewhere…
