+
+If you're using the [S3 Plugin](../add-plugins/s3.md) and, when you upload an image, you receive the following error on your Medusa server:
+
+```bash

+```
+
+Try the following:
+
+1. Go to your S3 Bucket, then choose the Permissions tab.
+2. Scroll to Object Ownership and click the Edit button.
+3. Select ACLs enabled and choose for Object Ownership the radio button Bucket owner preferred.
+4. Click the Save Changes.
+
+Try uploading again after making this change. Upload should be successful.
