I have used the CalDav option to sync calendars between OwnCloud NAS and Windows 7 and Android devices and until I updated to SM v2.17 the sync worked perfectly. Since the update, that required a Lightning update to v2.2b1, adding or editing an event in Lightning (Win 7 PCs) writes the event to the CalDav server but fails to show the event on the Lightning calendar. The events appear as normal on the Android devices. This problem occurs in existing calendars and in my attempts at starting new calendars. In the hope that the latest beta test versions of SM and Lightning might have addressed this problem I forced updates to SM v2.18 and Lightning v2.3b1 but without success. This is a significant problem for me and I would appreciate any information regarding a solution or a workaround. _______________________________________________ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey
