Hi, I followed the securing ISPConfig with StartSSL free cert, and everything went just OK as usual with the great tutos here! As I'm hosting the same domain as the server, I should be able to apply the same certificate to the domain created by ISPConfog through SSL tab in site edit. The problem is I needed to create a subdomain, and as suggested, just created a new site pointing to it, so I have two sites, site.com and the subdomain (another ispconfig site) it.site.com If I apply the SSL certificate (created for site.com and subdomain it.site.com through StartSSL) to it.site.com, Apache refuses to start with suspicious error log: Is my new Cert applyed to this subdomain causing this? Thanks a lot! PS: Of course, if I erase sites enables it.domain.com.vhost apache starts ok, and if I regenerate the certs through ISPConfig interface the site works ok, but, of course, with SSL warnings.
