Backend nicht mehr erreichbar - hat sich erledigt. Wie bekommt man das hier zu?

Hi, 

 

ich komme nicht mehr ins Backend bei dieser Fehlermeldung:

 

Ups! Ein Fehler ist aufgetreten!

Die nachfolgenden Hinweise sollten Ihnen weiterhelfen.

The provided CSRF-Token is invalid. If you’re sure that the request to path „/backend/Login?file=app&no-cache=1540565458“ should be valid, the called controller action needs to be whitelisted using the CSRFWhitelistAware interface. in engine/Shopware/Components/CSRFTokenValidator.php on line 109
