I have just encountered the same issues. My game is a pretty simple version of pong so I'm not sure what is going on. It validated but gave me 10 Warnings. 9 of which were CSP violations.
I also get a:
JavaScript Compile-Time Error
Warning: A compile-time error in the JavaScript halted validation of that file.
Message: missing ; before statement
data.js
Anyone at all have any ideas as this came straight out of C2's open web export.?
Cheers
Dave
