After the Kobal Update from Dec 22, nobody on my kolab server an read or write Calendar / Contacts. In Roundcube, you can see the error message "the requested contact was not found".
In the error log (/var/log/roundcubemail/errors.log), i see this:
[31-Dec-2022 19:15:20 Europe/Berlin] PHP Fatal error: Uncaught Error: Call to undefined method SWIG\_p_Kolab__cDateTime::isValid() in /usr/share/roundcubemail/plugins/libkolab/lib/kolab_format.php:279 Stack trace: #0 /usr/share/roundcubemail/plugins/libkolab/lib/kolab_format.php(593): kolab_format::php_datetime() #1 /usr/share/roundcubemail/plugins/libkolab/lib/kolab_format_xcal.php(110): kolab_format->to_array() #2 /usr/share/roundcubemail/plugins/libkolab/lib/kolab_format_event.php(151): kolab_format_xcal->to_array() #3 /usr/share/roundcubemail/plugins/libkolab/lib/kolab_storage_folder.php(563): kolab_format_event->to_array() #4 /usr/share/roundcubemail/plugins/libkolab/lib/kolab_storage_cache.php(1111): kolab_storage_folder->read_object() #5 /usr/share/roundcubemail/plugins/libkolab/lib/kolab_storage_cache.php(812): kolab_storage_cache->_unserialize() #6 /usr/share/roundcubemail/plugins/libkolab/lib/kolab_storage_folder.php(302): kolab_storage_cache->select() #7 /usr/share/roundcubemail/plugins/calendar/drivers/kolab/kolab_calendar.php(319): kolab_storage_fol in /usr/share/roundcubemail/plugins/libkolab/lib/kolab_format.php on line 279
