Hello all, I'm having an issue with the Libris ILL install and wondered if anyone could help. I get a 500 error going to the ILL requests -> new request (Libris). This is the error I see in plack-error.log after the first attempt after an update or reboot: Can't locate YAML/Syck.pm in @INC (you may need to install the YAML::Syck module) (@INC contains: /usr/share/koha/lib /usr/share/koha/installer /usr/share/koha/lib/installer /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.32.1 /usr/local/share/perl/5.32.1 /usr/lib/x86_64-linux-gnu/perl5/5.32 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl-base /usr/lib/x86_64-linux-gnu/perl/5.32 /usr/share/perl/5.32 /usr/local/lib/site_perl) at /usr/share/koha/lib/Koha/Illbackends/Libris/Base.pm line 23. BEGIN failed--compilation aborted at /usr/share/koha/lib/Koha/Illbackends/Libris/Base.pm line 23. Compilation failed in require at /usr/share/koha/lib/Koha/Illrequest.pm line 320. And these two lines appear in every further attempt to get on the page: Attempt to reload Koha/Illbackends/Libris/Base.pm aborted. Compilation failed in require at /usr/share/koha/lib/Koha/Illrequest.pm line 320. I added Freeform first, and that works fine. I followed the basic instructions on the Koha ILL backends page and the additional instructions for Libris on the github page for configuration. Kind Regards Christina
