I tried to install Wordpress on my Ubuntu 12.10 server, and I think I got something wrong, because now if I go to wordpress.mysite.com I get a page lists the index for the /var/www contents that has the following. How can I remove the wordpress.mysite.com? Not sure if it is a symbolic link, or sub-domain, but I want to get rid of it. Thanks in advance!
