While I was switching the server's software from forge to java, I needed to create a backup file so me and my friends can play on the server's world using the java software. I got the backup file from the download button on aternos.org/worlds/ and I received a compressed (zipped) folder file of the server's world. However when I uploaded the server file on a new server, I am given an error message saying "You are only allowed to upload .zip files!". Me and my friends are playing on Tluancher for more information if needed. Please respond as soon as possible. Thank you for your service!
