What could cause the problem and how to resolve it?

Works again - somehow PHP didn't work proberly. After restarting system it works again. Sorry for bothering you.

do you see the MessageFormatterMapper.php on your server in path <site>/vendor/nesbot/carbon/src/Carbon/MessageFormatter?
if not: does the <site>/vendor and its subdirs exist?

Hallo, wahrscheinlich hat es sich überschnitten - in Meldung 2 habe ich schon geschrieben, daß mein PHP nicht mehr funktioniert hat (nur um Fehler 40 nicht erwähnen zu müssen).

Aber Danke für Deine, wie immer, schnelle Antwort.
Schönes Wochenende

ja, ich habs nach dem (etwas verzögerten) Abschicken schon gesehen. Ebenso schönes Wochenende und Karneval oder Fasnet, je nachdem, wo du bist.
