Hallo Community,

&nbsp;

folgende Meldung erscheint nach erfolgreicher Installation:

**Fatal error** : Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class „StateMachineHistoryDefinition“ from namespace „Shopware\Core\System\StateMachine\Aggregation\StateMachineHistory“. Did you forget a „use“ statement for another namespace? in /home/op003rz4/www/home/shopware6/var/cache/prod\_k379092f7\_pd41d8cd9/Container8OxhZL5/srcShopware\_Production\_KernelProdContainer.php:1645 Stack trace: #0 /home/op003rz4/www/home/shopware6/var/cache/prod\_k379092f7\_pd41d8cd9/Container8OxhZL5/srcShopware\_Production\_KernelProdContainer.php(2457): Container8OxhZL5\srcShopware\_Production\_KernelProdContainer-\>getStateMachineHistoryDefinitionService() #1 /home/op003rz4/www/home/shopware6/var/cache/prod\_k379092f7\_pd41d8cd9/Container8OxhZL5/srcShopware\_Production\_KernelProdContainer.php(2876): Container8OxhZL5\srcShopware\_Production\_KernelProdContainer-\>getStateMachineHistory\_RepositoryService() #2 /home/op003rz4/www/home/shopware6/var/cache/prod\_k379092f7\_pd41d8cd9/Container8OxhZL5/srcShopware\_Production\_Ke in **/home/op003rz4/www/home/shopware6/var/cache/prod\_k379092f7\_pd41d8cd9/Container8OxhZL5/srcShopware\_Production\_KernelProdContainer.php** on line **1645**

Habe jetzt im Ordner /var/cache den Cache geleert und nun kommt folgende Meldung, wenn man dann nochmals reloaded kommt wieder die Meldung von vorher (siehe oben):

Problem nun gelöst, die Datei StateMachineHistory/StateMachineHistoryDefinition.php&nbsp; hat im Ordner gefehlt, ist anscheinend beim FTP-Upload auf den Server nicht kopiert worden. Nun geht der Admin zum Aufrufen.

Verzichte doch auf den FTP upload und entpacke auf dem Server.  
Ich mache das so:  
&nbsp;

```
wget https://releases.shopware.com/sw6/install_6.0.0_ea2_1571125323.zip
unzip install_6.0.0_ea2_1571125323.zip 

```

Dauert nicht mal 5 Sekunden.
