I'm not sure what went wrong, here's what I did...
In admin login, I set the hostname to srv.domainname.com
Then I create an account called "myuser" and the directory is created as /home/myuser, I set the domain name as mw.domainname.com
I created a simple index.html at /home/myuser to test
I tried loading mw.domainname.com and it keeps loading the Webuzo default page, which is located here: /usr/local/apps/apache2/www/htdocs
mw.domainname.com doesn't load my index.html at all. I tried SMF app installation and it's still showing Webuzo default page.
How do I get my installation to show the content at /home/myuser when I load mw.websparks.sg? I have checked DNS, file manager, IP and nothing works.
