Your feed shows up fine in FF and in Chrome.
Well Feedburner is telling me it’s not a valid feed. And I can’t find my feed on any site I try to subscribe to.
http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fstvnandrw.com%2Fblog%2Frss show a valid feed.
But there is something set up wrong. http://stvnandrw.com/blog/ should work for rss validation but it doesn’t. To get it to validate you have to add rss or feed. It should be added automatically.
Where did you get the theme you are using?
It was a theme I created myself, which is why I’m sure there is something wrong with it, haha.
And I can’t find my feed on any site I try to subscribe to.
Your feed will only be on your site.
With a custom theme, there is no way to help you. Switch to the default theme, twentyfourteen and see what happens.
