Before you add any language content to your site, you must set the site’s default language. A site’s default language isn’t the same as the default language setting in your Salesforce org. This behavior is deliberate. Let’s say you have multiple sites and want a different default language for each. At the same time, you want your org default language to be consistent. With a separate default language for your org, it’s easy to set things up this way.
-
In Experience Builder, click
| Languages.
-
Select a language from the Default Site Language list.
Note If you plan to add Salesforce CMS content to your site, it’s important that the site and the CMS workspace have the same default language so that the content appears properly. If the default languages are different, translate the content in your CMS workspace into your default site language, then add the translated content to your site. - Optionally, click Edit display label, and change the way the selected language label appears. For example, you can use this opportunity to translate the language’s display label.
- Export site content.
- Change the default language.
- Import the exported file.
Changing the default language can overwrite existing translations. So you export first to preserve your original default language and your translations. After you change the default, you can import translations to restore them.
Here’s how it works. Let’s say you make English the default language and add French as a site language. After you add the translated French content, you decide to change the default site language to French. To preserve your original default language and existing translations, you must first export. Then, select French as the default site language, and import content back into the site.
