Hallo,

weis jemand was diese Fehlermeldung zu bedeuten hat:

&nbsp;

## 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=1576142975” should be valid, the called controller action needs to be whitelisted using the CSRFWhitelistAware interface. in engine/Shopware/Components/CSRFTokenValidator.php on line 102

Diese Fehlermeldung tritt ab und zu auf. Wenn ich das Backend dann wieder neu lade geht alles.

Bekomme auch manchmal einen Internal Server Error fehler gemeldet, wenn ich im Backend bin.

Ich tippe mal auf:

1. unsaubere Anpassung oder inkompatibles Plugin

2. nicht&nbsp;adäquates Hosting

Zu dem 500er Fehler (Internal Server Error) solltest Du auch was im Error-Log der Website finden.
