[Plugin: wp Time Machine] Backup to Dropbox Not Transferring

WP Time Machine v1.9.21 stopped transferring backups on my three weblogs to Dropbox about three weeks ago. Everything appears fine from the logs (see below), but when I click the Generate button from any of them, it runs for just a couple of seconds then claims it has been finished, but nothing gets uploaded. I have confirmed the password and user name are correct.

I do have a beta version of Dropbox running on one of my computers, but this issue happens on others that aren’t running that beta. That should be irrelevant, any way, as WP Time Machine isn’t running on my local computer.

I see on my website most of the files the log says it will transfer, though I haven’t found the wpTimeMachine-data-files.sql data file yet, as I don’t know where to look for it.

Any suggestions? Thanks, Gary

Here’s my log:
