This tutorial worked beautifully before StartSSL updated their website and the way things are setup now. Now, it has me download 2 .crt files and I'm not sure which one to use. Is there an updated tutorial somewhere or can someone help me out? I opened the "2_[mydomain].crt" file in a text editor and copied the contents. I followed the tutorial for everything, but it doesn't work. (I still get security errors in Chrome.) Please help.
Better use Letsencrypt today instead of startssl: https://www.howtoforge.com/community/threads/securing-your-server-with-lets-encrypt.75554/
