Due to a recent change I made to the site I had accidentally broken the game uploader. If you have tried to upload a game recently and had a problem when clicking the "Upload Game Files" button please try again as this issue has now been fixed. Thanks to AMGaming for letting me know about the issue.
Thanks,

Hey thanks so much for fixing that promptly. It's appreciated greatly. I just uploaded my first game I ever made in Construct 3. So far this site is really awesome!
