Hi anunja,
which Abook version are you using?

Hello!
Joomla 5.1.0
Alexandria Book Library 4.0.2

You are right!
To fix them you can modify your_site/components/com_abook/models/category.php line 390
from

Code Select Expand

if (sizeof($this->_children)) {to

Code Select Expand

if ($this->_children) {
After the change the error displayed will be "404 Category non found".

I will publish the fix to the next version of Abook.

In case of access to unauthorized content, perhaps it would be better to show the login form. I put this change on the todo list.

Grazie Federica! Io ho fatto la pagina con la forma di autorizzazione e con il link alla Alexandria category.
