hello! do you have a guide to buy an ssl and install it into a site in ispconfig? do you recommend a ssl cert company? thanks
There is a chapter on how to install ssl certs in the manual, you can download the manual here as howtoforge subscriber: https://www.howtoforge.com/download-the-ispconfig-3-manual I'm using mostly Comodo SSL certs because they are not so expensive, but GeoTrust or any other widely used SSL authority is fine as well. In most cases, a free Let's encrypt SSL certificate should be fine though, so you don't have to buy an SSL cert anymore to get a valid SSL encrypted site. For let's encrypt, just enable SSL and Let's encrypt checkbox of the website and ensure you have the current git-stable ISPConfig version installed due to a recent bug in certbot.
