Hallo, ob ich bei diesem Fehler wohl das Foreign Key Repair Tool anwenden soll? folgende Fehlermeldung tritt auf: Entity of type ‚Shopware\Models\Customer\Group‘ for IDs id(2) was not found in vendor/doctrine/orm/lib/Doctrine/ORM/EntityNotFoundException.php on line 47 Stack trace: #0 vendor/doctrine/orm/lib/Doctrine/ORM/Proxy/ProxyFactory.php(195): Doctrine\ORM\EntityNotFoundException::fromClassNameAndIdentifier(‚Shopware\Models…‘, Array) #1 var/cache/production\_201510221322/doctrine/proxies/\_\_CG\_\_ShopwareModelsCustomerGroup.php(208): Doctrine\ORM\Proxy\ProxyFactory-\>Doctrine\ORM\Proxy{closure}(Object(Shopware\Proxies\_\_CG\_\_\Shopware\Models\Customer\Group), ‚getKey‘, Array) #2 var/cache/production\_201510221322/doctrine/proxies/\_\_CG\_\_ShopwareModelsCustomerGroup.php(208): Closure-\>\_\_invoke(Object(Shopware\Proxies\_\_CG\_\_\Shopware\Models\Customer\Group), ‚getKey‘, Array) #3 Shopware/Bundle/StoreFrontBundle/Service/Core/ContextService.php(195): Shopware\Proxies\_\_CG\_\_\Shopware\Models\Customer\Group-\>getKey() #4 Shopware/Models/Shop/Shop.php(710): Shopware\Bundle\StoreFrontBundle\Service\Core\ContextService-\>initializeShopContext() #5 Shopware/Controllers/Backend/Article.php(4433): Shopware\Models\Shop\Shop-\>registerResources(Object(Shopware\_Proxies\_ShopwareBootstrapProxy)) #6 Enlight/Controller/Action.php(158): Shopware\_Controllers\_Backend\_Article-\>previewDetailAction() #7 Enlight/Controller/Dispatcher/Default.php(523): Enlight\_Controller\_Action-\>dispatch(‚previewDetailAc…‘) #8 Enlight/Controller/Front.php(227): Enlight\_Controller\_Dispatcher\_Default-\>dispatch(Object(Enlight\_Controller\_Request\_RequestHttp), Object(Enlight\_Controller\_Response\_ResponseHttp)) #9 Shopware/Kernel.php(148): Enlight\_Controller\_Front-\>dispatch() #10 vendor/symfony/http-kernel/HttpCache/HttpCache.php(492): Shopware\Kernel-\>handle(Object(Symfony\Component\HttpFoundation\Request), 1, true) #11 Shopware/Components/HttpCache/AppCache.php(255): Symfony\Component\HttpKernel\HttpCache\HttpCache-\>forward(Object(Symfony\Component\HttpFoundation\Request), true, NULL) #12 vendor/symfony/http-kernel/HttpCache/HttpCache.php(263): Shopware\Components\HttpCache\AppCache-\>forward(Object(Symfony\Component\HttpFoundation\Request), true) #13 Shopware/Components/HttpCache/AppCache.php(103): Symfony\Component\HttpKernel\HttpCache\HttpCache-\>pass(Object(Symfony\Component\HttpFoundation\Request), true) #14 shopware.php(101): Shopware\Components\HttpCache\AppCache-\>handle(Object(Symfony\Component\HttpFoundation\Request)) #15 {main} Beste Grüße Nicolas

Du solltest mal prüfen ob du deinem Shop eine Kundengruppe zugewiesen hast. Viele Grüße

Danke für den Hinweis, ja das hat geholfen. Ich hatte eine Kundengruppe gelöscht und danach wieder erstellt - Somit wurde wohl in der Grundeinstellung die Einstellung gelöscht. Beste Grüße Nicolas
