We're trying to catch up with all those support emails we've been getting. I think we're still about 6 days behind, but catching up!
In Console, there should be a search box. You can type OmniFocus in there and it will filter out messages from other apps.
To turn on some additional logging that might help, you can do the following:
1) Quit OmniFocus
2) Type the following line into Terminal and press return:
Code:
defaults write com.omnigroup.OmniFocus XMLFileManagerDebug -bool YES
3) Launch OmniFocus again
If you open up the OmniFocus Sync Preference pane and then sync, it will show a progress indicator.
