RSS Feed broken

I just got a WordPress site with the Coller Theme.

I can not get the RSS Feed address to work. When you plug it in, it says it doesn’t work. My website is: http://jenieats.com/

My host said this is what happens when he tries to validate it: http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fjenieats.com%2Ffeed%2F

He said to try turning my social media icons off and trying it but it still doesn’t work.

I want it to work so I can direct my old blog readers to the new site. Thank you so much for your help!
