rob69 on "[Plugin: BackWPup Free - WordPress Backup Plugin] "ERROR: S3 Service API: Access Denied" when using PHP 5.3 or 5.4"

Hi
I followed this post and I am using PHP 5.5.17. I have used the policy above but I get the error Ken is having:
<blockquote>Statement is missing required element - Statement "NO_ID-0" is missing "Principal" element</blockquote>`

I have also tried to create a policy directly in Amazon but no luck. Any pointer?
