site alias problem

Hi,

I have new installation of campsite 2.6.3 on Fedora Core 4  
(mysql-4.1.16, php-5.0.4, httpd-2.0.54), database was upgraded from  
2.1.6. Virtual hosts for apache are set correctly, the same for  
publication inside of campsite administration. But I can not open the  
website. Every time i get error: "Internal out of range error:  
invalid publication alias... ". I can access admin interface  
normally. In apache error log, I can find:
PHP Notice:  Undefined variable: argc in /usr/local/campsite/www- 
common/html/index.php on line 31
for every attempt to open the site. Installation was without any  
problems.

Can somebody help me with that?

Thank you,
Michal
