I just upgrade to ISPConfig 3.0.5. Work is fantastic, but I was waiting for this release because of the new subdomain-style, with a directory within main folder, not like older release, where a subdomain was a "ServerAlias". I think something I'm doing wrong, because the behavior is the same than the older one, and I'm not get a new folder, just a "ServerAlias" in domain config. The steps I follow are: Sites->Subdomains, I choose "No redirect" (I try with all options) and "Save", but I don't get the expected behaviour. Can somebody help me, please? PD: sorry for my english if some expresions are not correct...
You need to enable this feature under System > Interface > Main Config on the Sites tab (Create Subdomains as web site). Afterwards, there is a new menu entry "Subdomain (Vhost)" under Sites. This is all described in the manual, btw.
