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.

btw, this is what they state about the debian options:

OpenVPN
For freedom fighters
The only VPN to be trusted is the one you have full control over.
The server and client certificates are automatically generated and the client file sent via email to the customer after. Runs on port 443, which is almost always accessible. All logging is sent to /dev/null and DNS queries are made on the same server.

Wireguard
Also for freedom fighters
40-50% faster than OpenVPN.
Route all your traffic through an encrypted tunnel, perfect for bypassing internet controlled by a fascist government.

LEMP
Ready to use webserver
LEMP stands for Linux, nginx (pronounced Engine x), MySQL, and PHP. It comes preconfigured with an optimized PHP setup which can run, depending on the size of the server, load heavy sites. It is also good as a content delivery server for example advertisement banners, videos, or even a fileserver for files to download.

Nextcloud Server
Ready to use Nextcloud
Run your own cloud service.
Nextcloud, the next generation open source Enterprise File Sync and Share software, the server is optimized for high usage with Let's Encrypt https certificate.


@bitPickup mʕ•ﻌ•ʔm @Hank G ☑️ @Raroun @TupambAdmin

@Hypolite Petovan Hello. After lots more testing today, i now have 50% happy news!

• I've still never succeeded in receiving a DM in Masto that was sent from Friendica [both libranet.de AND a new venera.social account i made today], if i use the 4-tab popup post-composer windowlet, with my Masto handle listed in the Permissions tab as a Private Message. Every single time, the DM appears to Send ok from Friendica, but it simply never arrives in Masto. Otoh...
  
• Finally i have succeeded in sending DMs that DO arrive in Masto, using the Friendica "Envelope Icon" toolbar shortcut to https://libranet.de/message. The solution was exasperatingly simple, yet completely obscure to me for 36 hours coz i was relentlessly just blindly following posting "the Masto way", unaware that this is wrong in Friendica. Specifically in https://libranet.de/message, each previous time that i had tried unsuccessfully to send a DM, i had prefaced my Masto handle with "@", because in Masto that IS part of the handle. It was only today that finally i decided to see what would happen if i omitted that leading "@", at which point i was delighted but astonished to see that finally the autodetect kicked in, it successfully matched my correct handle, & consequently all my DMs now DO properly Send from both my Friendica accounts, AND get received in my Masto account. Phew & thank bloody goodness, coz this was driving me batty!

I'm still disappointed that #1 does not work for me, but very happy that at least #2 does.

As such, this certainly eliminates any possibility that my problem [#1 OR #2] might have been caused by a bug in the Dev version [libranet.de], given that i proved today that the problem equally occurred in the Stable version [venera.social] ... and now i know how to avoid/solve #2.

Thank you all for helping, & sorry that i was such a slow learner.
