Hmmm... the dynamic user profile has not been created properly. I wonder what caused that.
*looking*
Ah yes, I think I know what it was. There was an error in the SQL statement updating the profile.
You did make a backup, right? Because I have now added a safety to the update script in case it cannot move the appropriate user fields over in the new table for dynamic fields so it doesn't remove the fields in the users table (will be available in the CVS nightly tomorrow). However, that will not help you as the damage is done now.
A way to get something working so you can try out some more is to:
1. Open PHPMyAdmin or similar DB admin tool
2. Run this query:
INSERT INTO [prefix]_user_profile (profileid) SELECT uid FROM [prefix]_users
replace [prefix] with your database table prefix
3. Edit your account
However, the blank page with the configuration bothers me - could you try saving the configuration again, this time with PHP debug?
