RSS Feed Not Working

WordPress automatically updated to 4.3.1 yesterday afternoon and now my RSS feed is not working. In MailChimp it says the RSS feed address is not valid. I have tried all of the link addresses in the forum posts and none of them work.

I have been using FeedBurner (I know it hasn’t been supported for years, but it has worked for me with no problems) and now that feed link no longer works in MailChimp either.

What is my feed address then? I’m so confused. Does WordPress automatically generate a RSS feed? Where can I find that?

I’m using the Suffusion theme in WordPress 4.3.1.

Thanks!
