I've designed a few sites before, but I'm in the process of opening my first eCommerce site. I'm at the point where getting an SSL is the next task. I went to http://www.instantssl.com under some of the advice I've seen in these forums. I noticed the free 30-day trial certificate and decided to give it a try. After they approved me for the trial certificate, they sent me an email with the actual certificates and stuff with some links to the installation instructions. Well, I read in DH's KB how to install the main certificate and did so through the admin panel...everything went fine. Then I see in the instructions that there are other "intermediate" certificates to install. This is where I get hung up BIG TIME. I've copied the applicable part of the instructions below. You can also see the full instructions here.
I am having a hard time understanding exactly what to do. I have searched these forums and googled for about the past hour, and it turns out, I am the dumbest person to have ever tried to install a SSL because no one else has ever asked this question before, lol. Seriously, if anyone can throw me a bone here, or if you can just point me towards a good, concise resource, I'd really appreciate it.
Thanks in advance
