According to our Compatibility Index
, Akeeba Backup for Wordpress won't run on that version of Wordpress at all. It has to be at least 3.8 or higher.
That said, it seemed to be cruising along nicely for something that doesn't work. The log doesn't tell me much except that the backup crashed gracefully. That conflicts with the 510 error and the security policy message. The security message usually means you used too many resources. The cure is to slow the backup down so that it uses the resources over a longer period of time, hopefully avoiding the problem.
Please go to your Akeeba Backup Configuration page and try setting:
Minimum execution time: 1 seconds
Maximum execution time: 20 second
Execution time bias: 75%
If you still get the error, try
Minimum execution time: 5 seconds
Maximum execution time: 1 second
Execution time bias: 50%
