This happens only for 1 of the 3 books I have in my local Pressbooks. So if the warning does not "ring a bell", please just close this issue.

@thomasdumm Where was the book in question cloned from? Another book in your local development network?

thomasdumm commented 6 years ago

a while ago from https://delivros.pressbooks.pub

greatislander commented 6 years ago

@thomasdumm Is the original content still there and publicly accessible? This error seems to be a result of your Pressbooks install not being able to load the table of contents from the REST API of the source book.

https://delivros.pressbooks.pub/pwlo00117r4 I checked that license and visibility allow cloning.

thomasdumm commented 6 years ago

I cloned the book again and do not see the issue any more. So either there was an issue with the cloning function at the time I cloned the book or during clonig something went wrong.
