Hallo,

gerade habe ich das Update auf 5.4.5. gestartet und bekomme folgende Fehlermeldung:

* * *

Error

Received the following error message:  
Could not apply migration (Migrations\_Migration1223). Error: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry ‚1263-2‘ for key ‚element\_id‘&nbsp;

Please try to fix this error and restart the update.

Response

```
 {"valid":false,"errorMsg":"Could not apply migration (Migrations\_Migration1223). Error: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '1263-2' for key 'element\_id' "}

```

* * *

Leider kann ich nicht erkennen wo in der Datenbank der doppelte Eintrag vorliegt. Kann mir jemand helfen?

Vielen Dank und viele Grüße  
Paul

Schau mal in die Tabelle “s\_core\_config\_elements” und/oder “s\_core\_config\_element\_translations”.
