Velly Interllesting. Could you please do me a big favour and do the debug test on both your sites to see if you can see any difference in regards to the xml?
You are doing all the right things, and yes, the data should be xml (which is why I'd like you to do this same exersice on both sites).
There are three possibilities here...
1. The server isn't always returning valid xml for some reason (you should probably see the difference between your two sites).
2. The server is returning xml, but the xml tags are being stripped when displayed to screen. This is what happens when I use that test link using MS Explorer rather than Firefox.
3. Still a mystery.
Your findings could be very important and valuable clues, especially since you appear to be in a rare position to have two sites operational, one that exhibits a problem and the other doesn't. If these two sites consistantly behave this way I have a feeling that I will be relying heavily upon you to help me find the cause (and therefore the fix).
As you can imagine, since none of the sites that I maintain (or have direct access too) don't exhibit any troublesome behaviour it is going to be impossible for me to work alone to solve the issue, so any clues, no matter how small is most welcome.
Cheers

ps. I wonder if it has anything to do with wether the server access is via 'cURL' or the http (file) method. Which of these do you use on your sites?
