Thank you I think it's working now. I will test and see if it keeps working for the next couple of days.
One other quick question. My bucket is now set on public, but other buckets are not set on public, while still working with Joomla Amazon S3 plugin. The installations are less large though. So why are these working right of the bat without the public permissions, while this large bucket is not working without setting it to public? Thanks
EDIT: Also the changes you made regarding the updating of the file list, what do I need to change in the current download from the website? I want that change also in my other websites I use this plugin with.
