What was updated? I tried to check the update log but last mentions were from 2015-01-17 and I have done some mods to allow buckets to show up, so I’m a bit afraid to update.
Changing the endpoint on line 29 and 53 solves the issue of empty buckets. Could you Shaon update the plugin settings page so that you could input your amazon endpoint url there without the need of typing it into the php?
