Before you begin working with Visual Composer, review and confirm the following list items to ensure high quality and smooth functioning of the application:
Have you defined the systems that you need in the portal, along with an alias?
Have you been mapped as a user to the backend system?
If you intend to use web services, have you written down the name and URL? Have you checked if a user ID and password are required?
Has your administrator assigned you a VC Role? Have you received the appropriate VC Role permissions?
