PHP Atom feeds are not showing

I'm using PHP to generate feeds, which is working perfectly fine on my local development sandbox. Once I upload to the server, I get a blank page. I know the programming is correct, because it works fine on my local box. What do you think the problem might be? I'm not using any extra libraries, atleast I don'开发者_StackOverflowt think so. I put on error reporting and received no issues. Any ideas?

Make sure you are outputing the correct Content-type, also try to validate the feed using some third party online service. If you are really getting nothing check your server logs, there must be a silenced error.
