I finished installation without no errors. I used ISP-Server Setup - Ubuntu 5.10 "Breezy Badger" article to do it.
But now, after installation when I try to login with admin:admin I have this error message:
Warning: Cannot modify header information - headers already sent by (output started at /home/admispconfig/ispconfig/lib/config.inc.php:131) in /home/admispconfig/ispconfig/web/login/trylogin.php on line 51
Can you help me?
