To Repro:
1. Open this simple tutorial project (from the first 2 steps of ghost shooter tutorial)
http://www.mediafire.com/?2571yr51p7nwv46
2. Export project
3. Open the exported html in any browser (Chrome, Firefox, IE, all gave same error msg), I'm using xampp apache local server.
notes:
Previewing the project from Construct works fine,
problem only appears once i export the project.
