A posting on the website said the Pottermore Shop would soon welcome fans after being delayed from a planned October opening.
The site`s creators have been testing it and said they changed to a more "suitable" platform for the millions of expected visitors.
The posting did not say whether e-book versions of the seven "Harry Potter" novels will be available immediately.
The interactive site will let readers navigate through the stories of witchcraft and wizardry on which Rowling based her blockbuster books about the teenage wizard and his friends.
"So get ready to join the Pottermore journey - the wait is nearly over," the posting said.
