I've used HardForum's tech news link on my page for ages. Noticed the feed isn't showing anything. Is RSS still on?
 
Seems to work for me.

I was able to add and fetch a feed from this location, but I had to turn on recursive discovery (whatever that does) in my reader. What is the URL for the feed you are using?
 
That one works for me too.
Curl verbose output (note I get a 200 response):

The W3C RSS validator seems to think it's getting a webpage instead of a feed, I imagine it's also getting a 403 page (although it's not saying that).

I wonder if CloudFlare is intercepting or maybe DNS is failing somewhere?
Would be helpful if you could capture the HTTP handshake and other communication from your feed reader somehow. Maybe from the browser's debugger?
 
Thanks for looking. Let me see what I can find out on our end. This isn't really my wheelhouse.

I talked to the person keeping up our site and apparently Hostgator pushed some more updates at our Wordpress site sometime recently. May be related.

It was hard to tell what end the was problem was on initially because all major browsers stopped displaying rss feeds natively a few years ago. You wouldn't think a basic RSS widget could be broken very easily it has been happily displaying your feed for years.
 
So I went to the document validator and it showed indeed it was getting a 403 error. I enabled error page validation and looked at the source, and it's a hardforum generated page which apparently uses javascript to load a challenge form:
JavaScript: 
document.createElement('script');cpo.src = '/cdn-cgi/challenge-platform/h/g/orchestrate/chl_page/v1?ray=84d2249d198042eb';window._cf_chl_opt.cOgUHash

Of course your embedded feed couldn't complete the challenge, and XSS (or some other) protection probably prevented it loading anyway.
 
Please PM me your server IP; I'll check the firewall logs.
 
I agree with those that said the content-type on presentation isn't there. IMHO, the rss feeds "needs some love".
