There can be only one default language for the entire OpenText Vibe site. You select the default language when you install Vibe, as described in Planning the Default Locale and Logging Time Zone
in the OpenText Vibe 4.0.8 Installation Guide.
When you create Vibe users, you can select a locale for each user, which determines the language of each personal workspace. However, when users who speak various languages work together on a Vibe site, they can often see interface text that is not in their preferred language. Examples include:
Standardized text such as Home Workspace, Global Workspaces, Personal Workspaces, and Team Workspaces in the Workspace tree
Standardized group names, such as All Users
Login page
Although you cannot change standardized group names, such as All Users, you can rename the standardized workspaces to include multiple languages. Although the Vibe login page can be displayed in only one language, you can change the page’s default language.You must be logged in as the Vibe administrator in order to perform these tasks.
Browse to the workspace.
Click the Configure icon next to the workspace title, then click Edit Workspace.
In the Title field, add text in another language, then click OK.
The language of the Vibe login page is decided by the Guest user account. Because of this, you can display only one language for your entire Vibe site in the login page.
To change the language of the Guest user account, and therefore change the language that is displayed on the Vibe login page:
Navigate to the Guest workspace.
On the Profile page click Edit.
The User page is launched.
In the Locale drop-down list, select the language that you want to be displayed on your login page.
Users who log in as Guest view the Vibe site in the language that you select.
Click OK.
