I realised that in my registration form the "core" fields (First Name, Last Name, Username, E-mail, Password, Verify Password) are DOUBLED.
I tried to eliminate the comprofiler_fields table from mysql and upload it again with the new CB installation, but these fields remained doubled.
Still can't find out what the problem is..

Thank you in advance for any help
