I am having a issue with post processing uploading to Rackspace CloudFiles.
This worked fine when using version 3.11.4. But when I upgraded to version 4.0.2 I get 'Forbidden - Access was denied to this resource.'.
I verified this on a second site by ruining backup before and after update. I also rechecked all settings are correct.
Below is the only line in log the show a issue.
[140919 10:59:40] Failed to process file <root>/administrator/components/com_akeeba/backup/site-www.7sd.com.au-20140919-105752.jpa
