CakePHP中的Feeds错误返回“无效的xml声明”

Question

I get an error, whenever I try to open the feed on my web app built on CakePHP:

Invalid xml declaration.
Line: 2 Character: 3
<?xml version="1.0" encoding="UTF-8" ?>

I don't really know what else I can do to resolve this problem. I did not change anything in the default template of CakePHP. The weird part is that it is working fine on my local box and other two servers but giving error only on one server.

Answer 1

The XML declaration should be on line 1, not line 2. You are probably accidentally adding an extra newline somewhere. Check out your PHP files. There should be no blank lines after the closing ?> tags at the end of your files!
