Blank Page After Installation

[mert]

Hi there,

I reinstalled OS (Ubuntu 10.10), then followed "the perfect server" manual.

I got installed ISPConfig 3.

Now the problem is ISPConfig control panel doesn't show the menu etc. Only logo at the top seems OK. Sometimes some links show up but clicking on them directs to a blank page.

And now server doesn't respond any command via ssh.
-bash: fork: Cannot allocate memory

Is this a virtual machine or a physical server?

If you use OpenVZ, please post the output of

cat /proc/user_beancounters
