Hi When in Koha 24.05 trying to activate the system preference "ILLModule" it leads to error 500 when clicking Koha staff client menu "ILL requests" or clicking menu "About > System information". In file "/var/log/koha/<instancename>/plack-error.log" it says: Can't call method "GetPlugins" on an undefined value at /usr/share/koha/lib/Koha/ILL/Request/Config.pm line 118. This behavior appears in Koha 24.05.01 and 24.05.05 (but it works as expedted in 24.11) . Does anyone know the solution of this problem?
