Simply move all the files from the remote server, back to the data directory. Remove additions to the config.php and uninstall the addon.I need to disable (uninstall) this addon as to use the xenforo per default settings. How can i do that?
In the case you're using an Amazon S3 bucket, you can move all the files back using the AWS CLI. Installation guide here: http://docs.aws.amazon.com/cli/latest/userguide/installing.html
Once that's done, run "aws configure" and add your access key and secret key in. Then run "aws s3 sync s3://mybucket ." to download all of the files from the s3 bucket.
