Changing the system language
To change the system language of your instance of Publisher, contact your CSM.
To change the system language that just you see, navigate to your preferences via your Profile > My preferences:
The System preferences screen is displayed:
Click the Language dropdown:
Select the language you want and click Save. Your changes will be saved.
Setting your system default language
As a user, you can set your system language preference in your Profile > My preferences:
The My Preferences screen is displayed:
Click the drop-down in the System preferences section, and select the language you want your instance to be displayed in.
This is YOUR preference. It won't change the language for anyone else.
Click Save to save your changes. Your system will now be displayed in your chosen language.
When you change your system language, it slightly changes how the search works too. If, for example, your system is set to Spanish, when you do a search, the content shown in the search results will have the new default language as the priority. So content labelled (as shown above) as Spanish, will be displayed first, over content in any other language.
This does not exclude other languages from your search results.
