galery settings – display author – problem

Hi Hossni,

When i activate “galery settings – display author”, there appears a link on the page https://www.bookabooka.com/prentenboeken-overzicht/
but when I click it it navigates to a page that does not exist. (https://www.bookabooka.com/book-author/)

I guess this only works when you use the new “authors” entity??

The page I need help with: [log in to see the link]
