I use moodle 3.5 with admin access.
i created a new chapter to my book, its id is 10 and it is 1rst position in the TOC.
When i visit the page (unlog) , i got an error :
"Error reading chapter of book".
This is strange because others chapter and the root book are accessible !
but the 10th chapter got a bug!
as admin, i tried to clean the content, change its position, save, re-save but it did not solve the problem.
what is the strange bug ou missing part ?
And by the way, the documentation page is missing :
thank you for your help, i'm searching since a very long time....
