There is no default page type available. The global default
page type is not configured. The default document type for this library
does not support pages and attachments. You did not specify a document
type. Select a document type that supports pages and attachments when
you create the page. Contact your administrator to configure the global
default page type. Or use a different library that is configured with
a default document type that supports pages and attachments.
Explanation
You attempted to create a page without specifying
a document type. However, the default document type for the library
does not support pages and attachments and the global default page
document type is not configured. When you do not specify a document
type, first the library's default document type is used if it supports
pages and attachments, or else the global default page document type
is used. However, the global default document type for pages is not
configured.

type.
