I already have one domain installed and working for wordpress.org and I am trying to start a new blog so I went and bought another domain and transferred the DNS to my web host etc. but when I try to open the page http://www.mywebsite.com/wp-admin/install.php it won't work. My web host does allow multiple domains so I know that's not the issue and the wordpress software is already installed on my FTP program since I have another blog already setup. Is there maybe some settings I need to change so the new domain will work too?
Not sure what to do from here so if anyone could give me a step-by-step guide of exactly how to start a new blog with a new domain name I would appreciate it. Thanks in advance for any help.
