Yes the files are working fine. I have the same files working here – https://demo.appfinite.net/oasis/ and I’ve also just re-downloaded and tested on a local demo server as well. They are both working normally. I haven’t came across anyone else running into this issue either. I’m wondering if there is a problem with your host?
Can you try downloading from your account page – https://appfinite.com/my-account/downloads/ and then uploading again? I would download the latest version of the Oasis and give that a try.
If you would like for me to log in and upload them for you to see whats going on, just let me know. I’d be more than happy to help.
