Permission problems after applying fix

[djtech]

I followed all steps on a fresh install of Ubuntu 9.10 and applied the permission fix (ticket 2247) and was finally able to install ispCP Omega. However, I found that all permissions under /var/www were root:root and I could not access anything in the browser. I ran chown -R www-data:root to the /var/www directory and now I can finally see the under maintenance page with the logo, but there are a bunch of errors at the top of the page and I cannot get any further. The errors are:

Warning: session_start() [function.session-start]: open(/var/www/ispcp/gui/phptmp/sess_Ypnt9AU5Xd0mYMWCpp0baRfMLQ8, O_RDWR) failed: Permission denied (13) in /var/www/ispcp/gui/include/ispcp-lib.php on line 43

Any ideas?
