Site is going crazy with redirects…

Paintballguns.net is experiencing major problems. My friends pointed it out to me.

The front page displays random posts/nothing every few minutes. Now the page loads with no template.

I’m getting this error in IE7: Internet Explorer cannot display this feed

Internet Explorer does not support feeds with DTDs.

In firefox it seems to be working SOMETIMES.

What’s going on? I can’t think of anything I’ve done recently that could have caused this.

Am I being attacked?

I’m 100% clueless. I checked with my host (bluehost) and they said everything is fine on their site.

Any help is appreciated
