RSS not working.

Hey,

I’m newish to making websites and I’m not a coder so I don’t understand a lot of how the things work.

But my RSS feed doesn’t seem to be working. When I click on it it shows the message: “This XML file does not appear to have any style information associated with it. The document tree is shown below.” and then there is a lot of code underneath.

How can I fix this problem?
