I use WP 3.1 and BackWPup 1.5.1 with the DropBox method.
The backup takes 30s and the zip file is uploaded to my Dropbox account, but each time I have a "Job XXXX already running!!!" error.
Then, I go to the Logs page, I see the backup status is OK but there's another line with a log with an error status.
Then, I go to the Jobs page, clear the job, return to the Logs page, and my previously green status is now with an error.
Anyways, it's not a big deal because the backup works, but this error didn't appear with the previous version of BackWPup (not sure I had the 1.5).
If someone has an idea...
PS : thx for the "export" capability, useful for my custom roles :) (but still some "10")
