[Serusers] serweb PHP errors

[PJR]

On Fedora core 3 with all needed packages installed and config.php
configured properly I can't login to serweb user_intrface or admin

When I first load the user or admin index.php I get many errors in
apache error logs like the following:

[client 192.168.25.2] PHP Notice:  Undefined index:  extrahtml in /var/www/html/phplib/oohforms.inc on line 72, referer: http://192.168.25.3/iptel/user/
[client 192.168.25.2] PHP Notice:  Undefined property:  isfile in /var/www/html/phplib/oohforms.inc on line 250, referer: http://192.168.25.3/iptel/user/
[client 192.168.25.2] PHP Notice:  Undefined property:  hidden in /var/www/html/phplib/oohforms.inc on line 253, referer: http://192.168.25.3/iptel/user/

[client 192.168.25.2] PHP Notice:  Undefined index:  frozen in /var/www/html/phplib/oohforms.inc on line 284, referer: http://192.168.25.3/iptel/user/

When I enter username/passwd and submit I get more errors in logs 
(Notice, index frozen etc.) and also A Bad Username or Password message 
and I return to login screen. There is nothing wrong with passwords, and 
I can connect to ser db with mysql client just fine.

I use serweb_2004-07-27 and ser-0.8.14.
I have the vars in php.ini according to the instractions.

Please point me to any possible solution.

Thanks.
