Php warnings when using w/ Amazon S3 Media

I really love this plugin! Everything seemed to work fine but since adding Amazon S3 for y media galleries but I’m getting errors on each post that’s pulling images from S3: https://welikenailpolish.com/2013/11/ive-got-a-crush-on-you/

It looks like it’s using the folder url for the image src instead of the full path, though it’s linking to the right media file. Go figure!

Any thoughts? It’s displaying perfectly & without warnings on this post https://welikenailpolish.com/2013/07/orly-passion-fruit/ but that’s using images that are still in the regular wp-uploads folder on the server.

This is what I’m using for S3: https://www.ads-software.com/plugins/amazon-s3-and-cloudfront/
