When I try to upload an image to a post in my forum, it fails to upload the image and I get an error message
> Unsupported value for canned acl ‘public-read’
This looks like an S3 error, but I have “enable s3 uploads” disabled in the file settings. I don’t want to upload images to S3. I have `DISCOURSE_USE_S3` set to `true` in `app.yml`, but this is for daily S3 backups.
Does anyone see anything wrong with my configuration? Thanks!

But it’s not. `DISCOURSE_USE_S3` is for uploads.

I set it to `false` and rebuilt the container, but it didn’t seem to fix the error or upload failure. I re-enabled it, but I’ll try it again.

`DISCOURSE_USE_S3` is now false, and the container is rebuild, but it’s still showing the original error message.
I noticed this message appears in my admin dashboard.
> The server is configured to upload files to S3, but there is no S3 CDN configured. This can lead to expensive S3 costs and slower site performance. [See “Using Object Storage for Uploads” to learn more](https://meta.discourse.org/t/-/148916).
But I don’t want to upload files to S3. How do I disable it? Both `DISCOURSE_USE_S3` and “enable s3 uploads” are disabled.

Did you comment out the line in `app.yml`?

No, I set it to `false`. I’ll try commenting it out.

I’ve commented out `DISCOURSE_USE_S3` and all `DISCOURSE_S3_*` settings, and I can now upload images. However, I believe this will break the daily backups to S3. I suppose I can try commenting out _just_ `DISCOURSE_USE_S3`, waiting 24 hours, and checking whether both uploads without S3 and backups with S3 still work.

Looks like I must omit all `DISCOURSE_S3_*` settings to make uploads work. Is there a way to allow both S3 backups and _non_-S3 uploads to work in Discourse?
Here are my relevant `app.yml` variables for reference. Currently everything is commented out.
