I've just downloaded this plugin since it seems to fit perfectly to my needs. However after installing it, and pressing WP2D -> Back-up Log to start the backup, nothing happens.
All I can see is 'You have not run a backup yet. When you do you will see a log of it here.', after pressing start, you see 'Loading' for a second after which the first message appears again.
I've installed Error log - No errors are being shown and the log is empty. I've also installed Cron Viewer, and the dropbox functions are also listed there.
