Dear Ninja Brian,
Your posted workaround does not appear to resolve the issue. :( I have a MacBook (10.5.8), a MacPro (10.5.8), and an iPhone (OS 3.0.1). Ever since I've upgraded to OF v1.7.1, I've been unable to sync among my devices. I've tried creating a new folder on MobileMe, re-building, restoring, etc..., but nothing seems to work. Furthermore, I don't have iDisk syncing enabled on either computer.
If I only use my MacPro with OF v1.7.1, everything is fine. But when I add my MacBook, my MacBook gets this error on syncing:
The remote database appears to have been reset and is no longer able to reach transaction identifiers (some string)
Then when I add my iPhone, my MacPro gives me this error on syncing:
Unable to read document. No root transactions found in “https://idisk.me.com/USERNAME/Data/OmniFocus.ofocus/”
Then when I try to re-sync with my iPhone, my iPhone gets this error:
Unable to synchronize database with server. Unable to read document.
As you can see, syncing is now impossible among devices.
Please help.
