imp 3.0 problems

[basso]

I can't manage contacts, in the options addressbooks menu I receive this
error:

Warning: Uninitialized string offset: 0 in
/var/www/html/horde/imp/templates/prefs/sourceselect.inc on line 61
The file defining the contacts/sources call (%application%/lib/api.php)
is not recheable

Where have I to set the contact ?.

Another problems, I can't create subfolders, only one folder in my mail
server home directory?.
My OS il Linux 7.2, sendmail as mail, Imp 3.0 and Horde 2.0.


Someone can help me?
