[imp] Notice: Undefined index errors

[Cory at themattsons.net]

Hi,
I've just installed imp and am getting numerous errors.  I have a feeling
they are all related somehow, but am too much of a notice at the moment to
figure it out..  Any help would be greatly appreciated.
At the login page I'm getting the following errors.

Notice: Undefined index: alternate_login in
/var/www/html/mail/horde/login.php on line 95
Warning: Cannot add header information - headers alread sent by (output
started at /var/www/html/mail/horde/imp/login.php:95) in
/var/www/html/horde/lib/Secret.php on line 144
Notice: Undefined index: server in /var/www/html/mail/horde/login.php on

Notice: Undefined index: server in
/var/www/html/mail/horde/imp/templates/login/login.inc on line 127

After displaying all of the errors it prompts me to login, after
successfully logging in it allows me to get into my INBOX, however that
page has even more errors.

Once again, any help would be greatly appreciated..

Thanks in advance,

Cory
