2. When instance start, in the Basic Configuration page, change the default language to Dutch and save it.

3. Shut down the instance.

4. Restart the instance and set the password and security details. Now Instance default language is Dutch.

5. From Control Panel go to Publishing --> Staging --> Select Local Live staging --> activate staging for public and private pages and then select "all content types" then save.

Actual result: Staging configuration is not successful with errors

Expected Result: Staging should be successfully configured.
