XML feeds not working

[mnelson4]

I'm using buddypress 1.5.4 and was getting the following error when subscribing to any of the RSS feeds:
"This page contains the following errors: error on line 2 at column 6: XML declaration allowed only at the start of the document"
(in Chrome, in Safari I was getting a different error).
I inspected the feed's source and indeed found an extra blank line before the XML version declaration, which was invalidating the XML feed. So I hunted about, and found these blank lines at the start of the RSS feed files themselves (in buddypress/bp-activity/feeds). They occur at these lines:

---

header('Content-Type: text/xml; charset=' . get_option('blog_charset'), true);
header('Status: 200 OK');
?>
<?php echo '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>'; ?>

---

So I removed the extra line break to make the code look like this:

---

header('Content-Type: text/xml; charset=' . get_option('blog_charset'), true);
header('Status: 200 OK');
echo '<?xml version="1.0" encoding="'.get_option('blog_charset').'"?'.'>'; ?>

---

And it got rid of the error for me! Maybe you'll want to incorporate this change into newer versions?

Good catch. Let's do this right after 1.6.

How do I recreate this issue? Both Safari 6 and Chrome want me to install separate RSS feed readers, and Firefox doesn't throw an error.

(In [6348]) Remove whitespace potentially breaking XML feeds. Fixes #4315, props fanquake
