It’s a lower/upper case problem: `https://www.babylonjs.com/demos/productPage/` should be `https://www.babylonjs.com/Demos/ProductPage/`.

The url inside the PG can easily be fixed, but there are also some paths in the GUI snippet itself… I fixed it programmatically:

> **[Babylon.js Playground](https://playground.babylonjs.com/#H896c7%23143)**
>
> Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes

It would probably be better to fix the snippet, but I don’t know if it’s possible.

The links can be fixed in the snippet as well with a new version: [Babylon.js Gui Editor (babylonjs.com)](https://gui.babylonjs.com/#WFL50L#24) 🙂
