UPDATE: the problem is solved, and you should be able to access chapters normally again.
A needed security update to the HASA database is currently preventing story chapters from displaying.
Please note: no data has been lost!
The chapters are fine, and will be restored to view as soon as possible.
It is all a retrieval error, and Tech Support is working on it. It may be a few hours before the data is displaying correctly again.
We apologize for the inconvenience...
