RSS Parse error

I am getting this error:
http://www.scrapbit.com/feed/

XML Parsing Error: not well-formed
Location: http://www.scrapbit.com/feed/
Line Number 7, Column 122: xmlns:creativeCommons=”http://backend.userland.com/creativeCommonsRssModule” xmlns:media=”http://search.yahoo.com/mrss/”xmlns:itunes=”http://www.itunes.com/dtds/podcast-1.0.dtd”
——————————————————————————————————————————–

I think it’s because there’s no space on xmlns:itunes=”…

Where do I edit this? I went to wp-include fee-rss2.php but there’s nothing there that I can edit here:
<rss version=”2.0″
xmlns:content=”http://purl.org/rss/1.0/modules/content/&#8221;
xmlns:wfw=”http://wellformedweb.org/CommentAPI/&#8221;
xmlns:dc=”http://purl.org/dc/elements/1.1/&#8221;
<?php do_action(‘rss2_ns’); ?>
>

Thanks!
