Sync to Dropbox was working, now not

[steviec]

As the title says, I had set up a rule that synced my nested folder structure of documents on my hard drive to Dropbox and all worked great for a while. It has since stopped working for a reason I can't fathom. Below is the extract from the log:

Can anyone tell me (in relatively plain English) what I need to do to get this valuable rule working again? thanks!

Try turning on debug logging as outlined in the sticky article. It should output more information that will help here.
