Resolved WebGL Build showing blank default skybox

Hello,

I just attempted to upload a version of my 2D game to itch.io. However, as shown in the picture below, instead of rendering my game, only the default skybox is shown.

How do I go about fixing this? I have no sound in my game yet, so I'm not sure if it is running and not displaying, however, I have changed the background from the default blue below to black.

I had selected "HTML File" in itch.io, made a .zip of the folder containing the build files, and had uploaded that. Builds for windows work fine with no problems.

Thanks for your help, and have a great day!

 

for anyone else with this problem, I later found this thread, which worked for me:
