The forum must belong to a parent forum or category. If you have no existing forums, create a category first (by setting 'Act as Forum' to 'No') before creating a forum.

Remember when creating a new forum or category, you will need to specify if it a forum or a category by setting Act as a forum? wheter yes or no.

Read here for more details about creating forums and categories.
