I installed netmrg 0.15 but when I tried to login I get the messages
Warning Undefined variable _SESSION in /usr/local/var/www/netmrg/lib/auth.php on line 76
in the loginscreen and login with the netmrg-username and -password doesnot work.
We use PHP's so-called 'Superglobals
' which requires PHP 4.1.0 or later. Do you know what version of PHP you're running?
