Unity WebGL not loading

So I built my game to WebGL and uploaded it to Itch.io, but when I or my peers go to play it, it doesn't fully load. In the console I get this error:

 V 1.3.loader.js:1 Uncaught ReferenceError: unityFramework is not defined
     at HTMLScriptElement.n.onload (V 1.3.loader.js:1)

Here is an image:

If anyone could help me that would be great.,
