Thanks to Let’s Encrypt this site offers now a SSL connection. The installation of the certificate took literally two mouse clicks within the cPanel GUI of my web hoster 😃
The new URL is (obviously) https://pesche.schlau.ch
I’m aware that I still need to update many links (e.g. to embedded pictures). These will be fixed in the next days.
In fact there was not much to do for the links and embedded pictures. There was one external link I had to adapt, for the rest I just followed the instructions in the Wordpress Support Team Blog.
