Received "css was not loaded because its MIME type, “text/html”, is not “text/css” Error

Hello there,

I tried deploying my related Jekyll site with Render.com using the 'hyde' theme, and I'm currently getting this error in Chrome Developer Console using the CSS stylesheet:

The stylesheet https://musimatic.xyz/css/poole.css was not loaded because its MIME type, “text/html”, is not “text/css”. [musimatic.onrender.com](https://musimatic.onrender.com/)
The stylesheet https://musimatic.xyz/css/syntax.css was not loaded because its MIME type, “text/html”, is not “text/css”. [musimatic.onrender.com](https://musimatic.onrender.com/)
The stylesheet https://musimatic.xyz/css/hyde.css was not loaded because its MIME type, “text/html”, is not “text/css”. [musimatic.onrender.com](https://musimatic.onrender.com/)

Any ideas on why this is occurring?
