WordPress MU

When I visited http://hmar.net/feed/ I got this error message:

---
XML Parsing Error: xml declaration not at start of external entity
Location: http://hmar.net/feed/
Line Number 3, Column 1:<?xml version="1.0" encoding="UTF-8"?>
^
---

Also when I subscribe to the feed, it failed loading the posts.

Anybody suggestions how to fix this problem? Thanks.

Yes, I got this problem too.
Open a ticket please

Now, how do i open a ticket :-)

BTW, skcsknathan001 - how did you output:

-
There are 27 blogs and 21 users running on this server.
-

and

-
UserOnline
* 2 Users Online
* Users: 2 Guests
-

in your website? http://adadaa.com/

BTW, your http://adadaa.com/feed seems to work fine.

ooh..its the feed you are talking about.
Oh.. i thought it was the import/export xml file.
sorry my bad

To create tickets, visit
http://trac.mu.wordpress.org/
and use the same username & password to login there.

To display blog stats
=========
<?php
$stats = get_sitestats();
echo " There are <b>".$stats[ 'blogs' ]." blogs</b> and <b>".$stats[ 'users' ]." users</b> running on this server.
";
?>

UserOnline is a plugin
http://www.lesterchan.net/portfolio/programming.php

Warning: It creates table per blog.
What I did was put in plugins directory and only activated in main blogs.
AFTER install
activate "WP-UserOnline Widget" first and then "WP-UserOnline"

Any thoughts on how UserOnline could work across the entire set-up? That'd be cool.
