Fehler nach Update auf 4.2

Ich erhalte nach dem Update nun diese Fehlermeldung [quote]Fatal error: Uncaught exception ‘Symfony\Component\DependencyInjection\Exception\ParameterNotFoundException’ with message ‘The service “plugins” has a dependency on a non-existent parameter “shopware.plugins”.’ in /var/www/clients/client1/web1/web/vendor/symfony/dependency-injection/Symfony/Component/DependencyInjection/ParameterBag/ParameterBag.php:106 Stack trace: #0 /var/www/clients/client1/web1/web/vendor/symfony/dependency-injection/Symfony/Component/DependencyInjection/ParameterBag/ParameterBag.php(232): Symfony\Component\DependencyInjection\ParameterBag\ParameterBag->get(‘shopware.plugin…’) #1 /var/www/clients/client1/web1/web/vendor/symfony/dependency-injection/Symfony/Component/DependencyInjection/ParameterBag/ParameterBag.php(203): Symfony\Component\DependencyInjection\ParameterBag\ParameterBag->resolveString(’%shopware.plugi…’, Array) #2 /var/www/clients/client1/web1/web/vendor/symfony/dependency-injection/Symfony/Component/DependencyInjection/ParameterBag/ParameterBag.php(193): Symfony\Component\Dependency in /var/www/clients/client1/web1/web/vendor/symfony/dependency-injection/Symfony/Component/DependencyInjection/ParameterBag/ParameterBag.php on line 106 503 Service Unavailable [/quote] Leider finde ich zu diesem Problem keine Lösung. Der Shop lief vorhar unter 4.14 Problemlos. Hat kemand eine Idee was die Fehlermeldung bedeutet?
