Same here!
Since upgrade to V3.0.12
When I start the job I get ‘Job “DB Backup” started.’
There are no progress bars. The job refreshes with 0 secs.
The log file shows only [INFO] lines, the last being ‘[INFO] Backup file is: var/logfilepathname…’
File ‘backwpup-5f9d5a-working.php’ is left in ‘/public_html/wp-content/uploads/backwpup-35392’
There are no backups anywhere.
However, an exact copy works on my WAMP localhost! The backup completes and uploads to Dropbox. Two nice progress bars appear and slide across as expected.
Some of the old forum comments are now confusing, tending to suggest all sorts of remedies, but nothing works other than reverting back to Backwpup V2.0.17.
Can’t waste anymore time on this. I need to move on!
