To use translation with Site Studio you need to configure your website with the following settings: 

Enable the Content translation module

• Navigate to Extend
• Enable the Content Translation module.

Configure entities and bundles to be translated

• Navigate to Configuration > Regional and Language > Content language and translation
• Select the entities types to translate. For example select Content
  
  
  
   
• Scroll down and enable the bundles to translate. For example Basic Page.
  
  
  
   

• Uncheck the Layout canvas field against each bundle you have enabled.

  Important

  You must follow this step because you don't want to translate the field, but the underlying entity. Failure to follow this step before translating content will result in content referencing multiple Layout canvas entities which can result in potential loss of data.

  
   
• Enable translation for the Layout canvas entity type
  
  
  
   
• Check Hide non translatable fields on translation forms.
  

Layout canvas field settings

When configuring the Layout canvas field on an entity type the "Users may translate this field" checkbox must be unchecked. This is because the Layout canvas itself needs to be translated not the Layout canvas field on an entity type.
