[horde] [newbie] Signup problem again

[Dmitry Diskin]

Hello.

After signing up, I'm getting the message

A fatal error has occurred:
Unable to add extra user information when signing up.

Details have been logged for the administrator.

And logfile contains:
[emergency] [horde] Unable to add extra user information when signing up 
[on line 96 of "/home/dda/horde/lib/Signup.php"]

I use latest CVS sources (i.e. horde/lib/Signup.php,v 1.6 2003/04/16 
22:31:06) .

What should I check first?

Thanks,
Dmitry.
