Hi All, We have been using shibboleth IDP and we noticed that the logs stopped generating after we upgraded tomcat from 9.0.15 to 9.0.31. No changes have been made to logback.xml. I have also checked that logback-core, logback-classic and slf4j-api jar files are present. Can anyone please guide us on how to troubleshoot this issue. Thanks, Regards, Kshitij Chug
