The project isn't exactly the same when fork

I just forked this project PlayCanvas 3D HTML5 Game Engine
When I play the original project, I saw the texture in the light. But when I play my forked project, only circle light on the ground. Please check this image Imgur: The magic of the Internet

How can I fix it?

In Settings → Rendering

enable Cookies Enabled

That seems like a forking bug right? I gather this setting should be preserved when forking.

It’s disabled in the old project as well it seems, so not sure what’s happening.

Thank you. It works
