I'm having an issue where my media is not uploaded to Amazon S3, even though the relevant boxes are ticked on the plugin. The problem seems similar to these two posts (see: this thread and this thread), although as instructed, I'm starting a new forum thread to track this.
The URL of the media referenced in WordPress does not change either --- eg. it stays pointing to the local server. So it's behaving in the same way as you'd expect if the plugin was not working at all.
The list of buckets is shown in the configuration page correctly, so I know that my access details are correct. Here is a screenshot of the page with my settings:
Does anyone have any pointers on how this can be made to work?
