The symlinks could not be regenerated

[dtptiger]

Hallo,
"The symlinks could not be regenerated"
das ist aus dem Backend-Log, nach dem "Systemwartung/Daten bereinigen/Symlinks neu erstellen"

Und wenn ich mit dem manager die Pakete aktualisieren will kommt diese lange Fehlermeldung:

Es ist nicht wirklich dramatisch, die Website läuft, komisch ist mir aber scho etwas
Was ist da los?

Fragt dtptiger

[Spooky]

Überprüfe die Server Umgebung mit dem Contao Check.

[dtptiger]

Ich kann den check (Contao Check 12.0) aufrufen, der sagt PHP 7.1.13 und alles wäre in Ordnung, ich könne ausser Contao 2 alles installieren.
Der Check ist frisch ins system geladen.

A B E R wenn ich die bestehende Installation prüfen will, dan gibts einen 404 Fehler!

Puh ...

[tab]

Das kann der Check nicht überprüfen für Contao 4.
