The Server works so far, but going to /admon/site throws an error:

BTW. Sorry for not using some formatting (e.g., for code), but currently, I'm running from a live Slax on an ancient laptop with an exotic German keyboard.

New error message (of FRIO) about a folder created by the user root.

I haven't found the extensive conversation about this problem with @Hypolite Petovan yet but I'm quite sure that I changed all folders to ownership of user www-data before 28th of November of the smarty folder. Actually there was another conversation about ownership of folders and I changed all folders to be owned by root except storage and view that day on 02:45hs, the new folder owned by root at /view/smarty3/compiled/ like stated below was created on 3:50hs.

As for what I remember of all the conversations this shouldn't have happened.
