Hi,
There have already been two topics about this problem, but the problem has not been resolved.
The author's page displays a list of his books. Clicking on the book - error 404.
For categories and tags, everything works fine. Doesn't work for authors only.
Disabling Seo on the site helps. But this is not a solution to the problem, so this option is not considered.
Example page:
https://orient.spbu.ru/index.php/ru/avtory/2-vasilij-pavlovich-vasilev
Abook version 3.1.5.
How to fix?
