Hi all, very new to Silverstripe stepping into the real world of CMS's rather than hacking my way through Wordpress!
I have setup Multisites fine and the drop-down option is showing, so far so good. but I cant access the subsite page, i just get a failed to open page error. Im not sure exactly how to set the subdomain up.
Have you setup the virtual hosts configuration on your server to point "http://subsite.localhost/mysite/" to the http://localhost/mysite/ folder? If its a subdomain (and on apache at least) you need a ServerAlias for the Virtual host record of mysite.
For localhost you may also have to edit your hosts file to point the subdomains to your localhost like the following
# add entries to hosts file for subsites
