Can't add new content in Interactive Book

When I go to create a new interactive book, it won't give me the option to add new content. Also, I've noticed that content I've used before in the interactive book (essay tool for example) is no longer available to add into existing books I've created.

Hi smcook0720,

If you are the administrator of the account you need to enable Column as it is the backbone of Interactive Book. To do this go to Manage Organization -> Settings -> Content Type Settings and place a check "Allow" for Column. If you are not the administrator of the account please reach out to your administrator for assistance.
