The server record is created by the ispconfig installer and ispconfig can not work without it as it contains the configuration details of the system. If the server record is missing, then ispconfig is not fully installed and has to be reinstalled.
The most likely reason for your problem is a modified PHP setup or ther conflicting configuration as a server where you install ISPConfig should be empty (debian minimal system with just ssh installed ) and then follow the perfect setup guide from step 5when you start witha image from your vps provider. If you install ispconfig on a system that has already websites or a different controlpanel installed, then its likely that the system will not work properly.
In any case, you will have to uninstall ispconfig first by using the uninstall.php script which is in the ISPConfig install folder in the tar.gz file, then check your php configuration and remove everything that might be non standrard like your prepend script or any excluded php functions and then install ISPConfig again.
