Hello Bert,
What do you find when you investigate the images with the developer tools in the browser (Developer Tools -> Elements/Inspector)?
This sentence is confusing:
I tried to upload, but no luck. Whatever I upload, I always loose the css for some reason and end up with the raw html, which doesn’t show the problem.
How can you lose the CSS code and how can the website shown correctly without CSS code?
Let me now what you found.
