I should have assumed it’d be less than ideal after reviewing the recommended policy for creating the IAM user and and S3 bucket permissions, which, for the record, are terrible, awful, nobody in their right mind would ever recommend doing in the real world sort of bad, but I went ahead anyway. It says it’s syncing my existing assets, but, in several days now, it hasn’t managed to move a single file to the S3 bucket. Kinda lame…

I tested this plugin only to find out it could not be used on my site without paying for it. Uninstalled it and it leaves my site broke. Be aware not to install unless you know exactly what you are doing. Maria
