After our upgrade to Koha 20.11, we have noticed a couple of errors. I'm trying to track them down and understand the changes. - lockdir in XML configuration file I get a warning about lockdir missing from the XML file, even after adding the line. I added: <lockdir>/var/lock/koha</lockdir> to my /etc/koha-conf.xml file but the error is still showing up in the About Koha screen. Do I have to do something to clear it? Or did I miss something? - RabbitMQ as message broker Reading the documentation, the addition of RabbitMQ as a message broker is specifically done for PLACK. Do I really have to set up a local RabbitMQ or is there another workaround? What am I gaining that did not work before? Because adding another little piece of software is a bit of hassle. If it is needed, where do I find documentation on setup? The Wiki has nothing that I found to be worthwhile. And if it is not (yet) needed, then how do I remove the error?
