I installed an MU plugin that allows users to enter additional predefined fields on their profile like phone number, country, zip etc. This would appear on the "Your Profile" page. It use to work after extensive testing but after installing multi-db 256 - the fields are no longer showing up on new registrants - in fact network wide. Interesting though is that the custom fields appear on the main profile of the main blog and not on any of the subdomain blogs.
Any inputs would be greatly appreciated.
