To address this limitation newer releases of CalDAV-Sync, CardDAV-Sync and SmoothSync have a new option to log their debug info to a file. To enable this feature start the app, enter "Debug options" and enable "Log to file". This feature is disabled by default because writing an additional log file causes additional overhead and you should disable it again once the issue has been resolved.
