Dropbox stopped syncing

Last night, DTTG stopped syncing my databases. It had been working fine. Then for no reason I know of, I just get error messages in the DTTG log. Is there a new version of Dropbox that has broken DTTG syncing? It appears to work in my desktop DevonThink Pro Office.

Yes, Dropbox has made changes but please provide what the errors are so we can try to determine what’s going on. Thanks.
