This give a "Service Unavailable", after sudo service plinth start, I
get again the time-out or Bad Gateway

There are some changes in mods-enabled:
lrwxrwxrwx 1 root root 26 Mai 22 16:32 ssl.conf
-> ../mods-available/ssl.conf
lrwxrwxrwx 1 root root 26 Mai 22 16:32 ssl.load
-> ../mods-available/ssl.load
lrwxrwxrwx 1 root root 29 Mai 22 16:32 suexec.load
-> ../mods-available/suexec.load

"suexec" rings a bell when I installed ikisite, but I am not sure.

Probably not:
-rw-r--r-- 1 root root  7116 Apr 10 15:03 apache2.conf

So my guess are the mods, but I am not sure how to correct those. Are
there "templates".

I have to close this for today, have to get to work tomorrow early, but
I will work on it in the evening.
