My website now looks basic and the CSS or HTML is messed up.

My website used to look nice with a cool theme and modern now it looks like a basic 1990's website. I don't know how to describe it except it looks bad. I want my previous versions back. Can someone tell me what's going on. I don't know what to prompt. Please can you take a look at my project at pythagora, Thank you Walter

We are not involved with Pythagora, you will need to contact the folks running it.
