[pmwiki-users] RSS feed corrupted

[Ben Stallings]

Hi, folks.  At some point in the past two weeks, the RSS feed at one of 
my sites stopped working properly:

http://www.psduua.org/Site/AllRecentChanges?action=rss

Looking at the source of the resulting page with FireFox, and comparing 
it to valid RSS feeds like those at pmwiki.org, I'm not sure what the 
nature of the problem is... something to do with white space?  I thought 
  white space was ignored in XML.  Where would it be coming from, 
anyway?  I've checked several times to verify that all the scripts and 
pmwiki.php are the same version (the latest beta).  Any ideas?  --Ben
