The portal's Knowledge page "/kb_view2" will return an empty page if no knowledge base is associated with the Service Portal .
In order to associate a knowledge base to a service portal :
- Navigate to Service Portal > Portals and open the service portal record to configure.
- Make sure that the Knowledge Base field is filled in. This Knowledge Base will be used to render the kb_view2 page.
You can attach only one Knowledge Base per portal.
