I tried to install MU in a root directory but I am getting Error establishing a database connection.
I followed the installation instructions and when I access the index.php at first I was asked "$base is set to BASE when it should be the path like "/" or "/blogs/"", so I changed it to "/".
Then asked to change the VHOST to yes or no, so I changed it to yes which didn't work and then to no which again didn't work.
I am struggling for a week with these installations, which is supposed to be automatic and easy id you know your way around Wordpress...
