Could you please fucking fix your upload problem cause I lost like 2 hours of editing the body section because I couldn't upload my file, yes I have tried making it into both a .RAR and .ZIP. Unable to validate file upload (Error Code: 3)
Sorry, it probably relates to the filesize. If your connection is patchy or if the server has any issues at the time, which becomes more and more probable the longer the upload takes, you will get an error like this.
Consider either A) breaking the file apart into smaller essential and non-essential archives, B) uploading to google cloud and just including a small ZIP with the URL and install instructions or C) finding a very reliable high speed connection (>10mbps upstream, ethernet) and trying again.
