Yesterday afternoon (U.S. time) we discovered and fixed a server configuration error that was introduced during the v1.0 launch Tuesday morning that has likely been the cause of numerous mysterious errors (including events not syncing, duplicate events being created, and various error messages). Syncing should work properly now, but you may have to perform a client reset to return Spanning Sync to a consistent state. To do so:
- Open the Spanning Sync preference pane
- Click the "Reset…" button
- Check "Reset info on this computer"
- Click "OK"
If after performing this procedure you encounter any problems, please let us know by emailing us at firstname.lastname@example.org. As you can imagine, we've had a huge surge in the number of users and are working hard to address all problem reports as quickly as possible.
