I am running the latest ISPC and Debian GNU/Linux 7.10 (wheezy). I tried to do this tutorial for SSL before finding out that I should now be using Let's Encrypt. When I try to enable SSL and Let's Encrypt on the website that I use for the server, the boxes won't stay selected. I can't find any LE logs to try and identify the problem. Does it have something to do with the steps I did for the StartSSL stuff?
