I am getting the following error after the installation of RoundCube Webmail v0.1-20051021.

[28-Nov-2005 03:35:25] PHP Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /var/www/roundcubemail/program/include/bugs.inc:106) in /var/www/roundcubemail/program/include/main.inc on line 72

Any ideas are appreciated.
