FocusGTD no longer matches up with OmniFocus / no longer syncs

Synchronization issues can occur for a number of reasons. OmniFocus is storing updates to its database in a number of small files. Should one of these files get lost then it can happen that OmniFocus on the Mac no longer matches with the state of FocusGTD.

In such a case do the following:

1. Synchronize all clients (under the assumption that OmniFocus for Mac and iOS are still in sync) and make sure that they are up to date (otherwise non-synched tasks made on iOS might get lost)

2. In OmniFocus on the Mac, select File->Move Old Data to Archive

   

3. Select File->Replace Server Database... which will replace all data with the server with data from OmniFocus on your Mac

   

4. In FocusGTD Click on Settings

   

5. And choose "Delete Database"

   

6. Synchronize FocusGTD again
