Hallo liebe Community,
ich habe ein Contao 4.4.20 mit php 7.1.8
Seitdem ich das Contao von einem Arbeitsplatz auf einen anderen Umgezogen habe erhalte ich einen Fehler beim einloggen im Backend:
Internal Server Error
Was ist das Problem?
Attempted to call an undefined method named "parseFile" of class "Symfony\Component\Yaml\Parser".
Was läuft hier schief?
Sieht so aus als ob ihm hier eine Klasse fehlt?
Der Error.log sagt:
Code:

Update:
Wenn ich in der Datei: /Applications/MAMP/htdocs/buschner/vendor/symfony/symfony/src/Symfony/Component/Translation/Loader/YamlFileLoader.php die besagte Zeile 48 auskommentiere, dann funktioniert alles wieder.
