When troubleshooting it is wise to deactivate “ALL” plugins other than BP and maybe bbPress and reverting too either the Twenty Twelve theme or bp-default. Do not selectively keep certain plugins activated when troubleshooting because the one that is causing the issue may be the one you failed to deactivate. If the registration then works you can start reactivating each plugin individually while testing the registration process against it. When you find the one that caused the issue then you can either not use it, or request support from the plugins author.
