[imp] ERROR when configuring horde 3.0.4 under freebsd 5.3 and php4

[Fleischer]

Hi guys

I have installed IMP and now I'm trying to configure horde. When I go to
config.php throug the webinterface it gives me the following error.:

Notice: Undefined index: log in /usr/local/www/horde/lib/Horde.php on line
51

Warning: Cannot modify header information - headers already sent by (output
started at /usr/local/www/horde/lib/Horde.php:51) in
/usr/local/www/horde/lib/Horde.php on line 1332

Any ideas why this is so?

Thank you in advance.
