I installed multisite successfully (huzzah) and can see that there are two now. I went to my cpanel and created the sub-domain. But I'm still having trouble. I'm not sure how to:
"configure your DNS (to map the domain name to the server's IP address) and server (to map the domain name to the WordPress installation directory). WordPress will then map the domain name to the site."
Not all of my themes show up as options for the new site (Unifor en direct - fr.uniforlive.ca).
I look forward to your help!
